Exercise 18 Page 274

Let p represent the percent that 60.8 is of 32. Write and solve a percent equation using p.

Equation: p %* 32=60.8
Solution: p=190

Practice makes perfect

Let p represent the percent that 60.8 is of 32.

We can write a percent equation using p. p % * 32=60.8 We will solve this equation using the Multiplication and Division Property of Equality. Let's do it!

p % * 32=60.8

a %=a/100

p/100 * 32=60.8

a/c* b = a* b/c

p* 32/100 =60.8

32p/100 =60.8

LHS * 100=RHS* 100

32p/100 * 100 =60.8 * 100

a/100* 100 = a

32p=60.8 * 100

32p=6080

Next, we will use the Division Property of Equality to simplify the equation even further.

32p=6080

.LHS /32.=.RHS /32.

32p/32 = 6080/32

Simplify quotient

p = 6080/32

Calculate quotient

p=190

We have that 60.8 is 190 % of 32.
