Exercise 46 Page 150

Think of 185 as the whole and we are looking for what part of it 35 % is.

64.75

Practice makes perfect

We can find what part equals 35 % of 185 by using a percent proportion. a/b=p/100 Let's substitute b= 185 and p= 35 into the formula, then solve for a.

a/b=p/100

b= 185, p= 35

a/185=35/100

a/b=.a /5./.b /5.

a/185=7/20

LHS * 185=RHS* 185

a=7/20 * 185

MoveRightFacToNumOne

1/b* a = a/b

a=1295/20

Calculate quotient

a=64.75

Therefore, 35 % of 185 is 64.75.
