Find the Missing Numerator and Denominator

Mathematics
1 answer:
n200080 [17]2 years ago
7 0

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}

A direct variation function contains the points (2, 14) and (4, 28). Which equation represents the function?
IgorC [24]
Direct variation mean x =ky so y = x/k

(2,14) mean y = kx so 14 = k*2 so 14 = 7*2 so 14 = 14 
(4,28) mean y = kx so 28 = k*4 so 28 = 7*4 so 28 = 28

from these result that the 3rd choice is right sure
