Find the Missing Numerator and Denominator
n200080 [17]

Answer:

  missing denominator: 5

  missing numerator: 3

Step-by-step explanation:

You know the product of fractions is formed by multiplying numerators and multiplying denominators.

  \dfrac{3}{d}\times\dfrac{n}{4}=\dfrac{3n}{4d}=\dfrac{9}{20}

This gives rise to two equations:

  3n = 9   ⇒   n = 3

  4d = 20   ⇒   d = 5

The missing denominator is 5; the missing numerator is 3.

__

  \dfrac{3}{5}\times\dfrac{3}{4}=\dfrac{9}{20}
