NCERT class 7 mathematics chapter 2 – “Fractions and Decimals” teaches us two fractions are multiplied by multiplying their numerators and denominators separately. For the CBSE exams, practice multiple-choice questions (MCQs) to prepare for the objective questions. We have provided Class 7 MCQ Questions on “Fractions and Decimals” paired with comprehensive explanations. CBSE is emphasizing the role of MCQs as they assist in understanding the concepts completely.
As compared to subjective questions, MCQs are very different so practicing and understanding how to get appropriate answers in MCQs is very essential. To revise the main concepts, students should practice all the MCQs with the answers given. This will also help them familiarize themselves with the kinds of questions that might appear in the board exams.

- Two fractions are multiplied by multiplying their numerators and denominators separately and writing the product as (product of numerators)/ (product of denominators).
- A fraction acts as an operator ‘of.
- The product of two proper fractions is less than each of the fractions that are multiplied.
- The product of a proper and an improper fraction is less than the improper fraction and greater than the proper fraction.
