SUBTOPIC: MULTIPLICATION AND DIVISION OF FRACTIONS
MULTIPLICATION OF FRACTIONS:
STEP 1:Multiply the top numbers (the numerators).
STEP 2: Multiply the bottom numbers (the denominators).
STEP 3: Simplify the fraction if needed.
RECIPROCAL OF A FRACTION:
When the product of two numbers is 1, then each of the number is said to be the
reciprocal of the other. It is also called the multiplicative inverse.
When we multiply a number by its reciprocal we get 1.To get the reciprocal of a
fraction, just swap the Numerator and Denominator.
EXAMPLE:
Find the reciprocal of 3/5
Solution: Reciprocal of 3/5 = 5/3
