Multiplying 2 fractions involves multiplying both numerators divided by both denominators.
Numerator 1 x Numerator 2 | |
Denominator 1 x Denominator 2 |
Numerator 1 = 4,
Denominator 1 = 9,
Numerator 2 = 72,
Denominator 2 = 1, so we have:
4 x 72 | |
9 x 1 |
288 | |
9 |
(1/9) x 288 = 32
(1/9) x 9 = 1
Since our reduced answer is a whole number, we remove the one from the denominator and write it as:
Answer = 32
