Question

StartFraction 32 Over 8 EndFraction = StartFraction 28 Over x EndFraction

a.
x = 4
c.
x = 8
b.
x = 28
d.
x = 7

Answer 1

d. x = 7

Explanation:

`(32)/(8) = (28)/(x)`

Cross multiply, the denominator "8" is multiplied by numerator "28", while the numerator "32" is multiplied by denominator "x":

8 * 28 = 224

32 * x = 32x

`32x = 224`

Divide both sides by 32:

`(32)/(32) = (224)/(32)`

[x = 7]
