Test: Fractions - 2 - Class 4 MCQ

To add fractions with different denominators, you need to find the least common multiple (LCM) of the denominators and make them the same.

When you add 2/3 and 8/3, you add the numerators (2 + 8 = 10) and keep the denominator the same (3).

To subtract fractions with different denominators, you need to find the least common multiple (LCM) of the denominators and make them the same.

2/3-3/4 = 8-9/12 = -1/12

To multiply two fractions, you multiply the numerators together and the denominators together.

Now, we can simplify this fraction by dividing both the numerator and denominator by their greatest common divisor, which is 3.

= (6 ÷ 3) / (21 ÷ 3)

= 2/7

So, the result of multiplying 2/3 and 3/7 is 2/7.

To divide one fraction by another, you multiply the numerator of the first fraction by the denominator of the second fraction and vice versa.

When you divide 2/3 by 4/5, you multiply the numerator of the first fraction (2) by the denominator of the second fraction (5) and the numerator of the second fraction (4) by the denominator of the first fraction (3). This results in (2 * 5)/(3 * 4) = 10/12.

A mixed fraction is a combination of a whole number and a proper fraction.

To convert a mixed fraction to an improper fraction, you multiply the whole number part by the denominator, then add the numerator and write it over the denominator.
