Y = kx

(i) 8 = k(-6)
k = -4/3
=> equation ： y=(-4/3)x

(ii) y = (-4/3)(-2)
y= 8/3

12+6x was subtracted from the left but only 12 was subtracted from the right.

6x and 6 are not equal unless x=1

X=-11/15

6/12=1/2
Therefore 6/12 is equal to 50/100 or 50%

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.

__

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