Exercise 8 Page 353

We want to find the fraction form of the given ratio. The ratio is in the form of part out of whole. We can write part as a numerator and whole as a denominator of a fraction. 72out of 96 → 72/96Now, we can rewrite this fraction as an equivalent percent p by setting up a proportion. A part of a whole is equal to the ratio of a percent out of 100. 72/96 = p/100 Let's solve the equation for p. We will simplify the fraction on the left-hand side of the equation. Then, we will use the Multiplication Property of Equality.

72/96 = p/100

a/b=.a /24./.b /24.

72/24/96/24 = p/100

CalcQuot

Calculate quotient

3/4 = p/100

MultEqn

LHS * 100=RHS* 100

3/4* 100 = p/100* 100

DenomMultFracToNumber

100 * a/100= a

3/4* 100 = p

MoveRightFacToNum

a/c* b = a* b/c

300/4 = p

Calculate quotient

75 = p

RearrangeEqn

Rearrange equation

p = 75

We found that the equivalent percent is 75 %.
