Elementary students spend years trying to master arithmetic. Teens struggle with the shift to algebra and its use of variables. High-school students must face diverse challenges like geometry, more advanced algebra, and calculus. Even parents experience frustration as they struggle to recall and apply concepts they had mastered as young adults, rendering them incapable of providing math help for their children. Whether you need top Math tutors in Boston, Math tutors in Detroit, or top Math tutors in Dallas Fort Worth, working with a pro may take your studies to the next level. The truth is, everyone struggles with math at one time or another. Students, especially at the high-school level, have to balance challenging coursework with the demands of other courses and extracurricular activities. Illness and school absences can leave gaps in a student’s instruction that lead to confusion as more advanced material is presented. Certain concepts that are notoriously difficult to master, such as fractions and the basics of algebra, persist throughout high school courses, and if not mastered upon introduction, can hinder a student’s ability to learn new concepts in later courses. Even students confident in their math skills eventually find a course or concept incomprehensible as they reach advanced math classes. In other words, no matter what your age or ability, everyone eventually needs help with math. Varsity Tutors offers resources like free Math Diagnostic Tests to help with your self-paced study, or you may want to consider a Math tutor. Varsity Tutors is happy to offer free practice tests for all levels of math education. Students can take any one of hundreds of our tests that range from basic arithmetic to calculus. These tests are conveniently organized by course name (e.g. Algebra 1, Geometry, etc.) and concept (e.g. “How to graph a function”). Students can select specific concepts with which they are struggling or concepts that they are trying to master. Students can even use these concept-based practice tests to identify areas in which they may not have realized they were struggling. For instance, if a student is struggling with his or her Algebra 1 course, he or she can take practice tests based on broad algebra concepts such as equations and graphing and continue to practice in more specific subcategories of these concepts. In this way, students can more clearly differentiate between those areas that they fully understand and those that could use additional practice. Better yet, each question comes with a full written explanation. This allows students to not only see what they did wrong, but provides the student with step-by-step instructions on how to solve each problem. In addition to the Math Practice Tests and Math tutoring, you may also want to consider taking some of our Math Flashcards. Varsity Tutors’ Learning Tools also offer dozens of Full-Length Math Practice Tests. The longer format of the complete practice tests can help students track and work on their problem-solving pace and endurance. Just as on the results pages for the concept-specific practice tests, the results for these longer tests also include a variety of scoring metrics, detailed explanations of the correct answers, and links to more practice available through other Learning Tools. These free online Practice Tests can assist any student in creating a personalized mathematics review plan, too, as the results show which of the concepts they already understand and which concepts may need additional review. After reviewing the skills that need work, students can take another Full-Length Math Practice Test to check their progress and further refine their study plan. Once a student creates a Learning Tools account, they can also track their progress on all of their tests. Students can view their improvement as they begin getting more difficult questions correct or move on to more advanced concepts. They can also share their results with tutors and parents, or even their math teacher. Create a Varsity Tutors Learning Tools account today, and get started on a path to better understanding math!

BILANGAN PECAHAN UNTUK MATEMATIKA SMP

Pencapaian belajar adik-adik tentang Bilangan Pecahan adalah mampu memahami dan dapat melakukan operasi hitung bilangan pecahan dalam pemecahan masalah. Operasi yang dimaksud adalah Aritmatika-MatematikaDasar berupa penjumlahan, pengurangan, perkalian, dan pembagian. Masalah-masalah yang coba diselesaikan dengan melibatkan pecahan apapun itu yang terkait dengan soal matematika ataupun masalah dalam kehidupan sehari-hari.

Sudah tau kan ?

Untuk mengetahui pribadi seseorang lebih jauh, tentunya kita perlu untuk berkenalan terlebih dahulu dengannya. Mulai dengan mengetahui nama, tempat tinggal, alamat sekolah, dan sebagainya. Setelah itu barulah kita mengetahui seperti apakah teman kita, apakah baik atau buruk. Teman yang baik tentunya akan membuat kita suka dan senang berteman dengannya. Nah seperti itu juga gambaran dalam mempelajari matematika. Mempelajari matematika haruslah dimulai dengan mengenal, menyukai, dan mencintainya. Mengetahui pengertiannya, bahasannya, sampai kepada mempelajari materinya. Tak terkecuali dengan materi ini, kita perlu untuk mengenal apa yang dimaksud dengan BILANGAN PECAHAN. Sekarang mari kita berkenalan dengan bilangan pecahan.

1) Pengertian Pecahan

Pecahan adalah suatu bilangan yang berbentuk

(dibaca "a per b") dengan b tidak sama dengan 0 (nol), a disebut pembilang dan b disebut penyebut. Pecahan juga dapat dipandang sebagai hasil bagi dari dua Bilangan Bulat a dan b dengan b bukan faktor dari a.

Contoh :

(3 bukan faktor dari 4)

2). Bilangan Pecahan yang Senilai

Suatu bilangan pecahan dikatakan senilai jika pembilang atau penyebutnya dikalikan atau dibagi dengan bilangan yang sama.

Contoh:

senilai dengan

karena 2x5=10 dan 3x5=15

dan

senilai dengan

karena 15:5=3 dan 25:5=5

Contoh Penerapan:

50% dari 24 adalah

dari 24 diartikan sebagai:

Catatan:

senilai dengan
