Complete these exercises to review skills you will need for this chapter.

Write each fraction as a decimal.

Question 1.
$$\frac{1}{8}$$ ________
Given,
$$\frac{1}{8}$$
Convert from fraction to the decimal.
= 1 ÷ 8
= 0.125

Question 2.
$$\frac{0.3}{0.5}$$ ________
Given,
$$\frac{0.3}{0.5}$$
Convert from fraction to the decimal.
$$\frac{3}{10}$$ ÷ $$\frac{5}{10}$$ = $$\frac{3}{5}$$ = 0.6

Question 3.
$$\frac{0.13}{0.8}$$ ________
Given,
$$\frac{0.13}{0.8}$$
Convert from fraction to decimal.
$$\frac{13}{10}$$ ÷ $$\frac{8}{10}$$ = $$\frac{13}{8}$$ = 1.625

Question 4.
$$\frac{0.39}{0.52}$$ ________
Given,
$$\frac{0.39}{0.52}$$
Convert from fraction to the decimal.
$$\frac{39}{100}$$ ÷ $$\frac{52}{100}$$ = $$\frac{39}{52}$$ = 0.75

Solve each equation using the inverse operation.

Question 5.
7p = 28 __________________
7p = 28 p is multiplied by 7
$$\frac{7 p}{7}$$ = $$\frac{28}{7}$$ To solve the equation, use the inverse operation, division.
p = 4

Question 6.
h – 13 = 5 ________
h – 3 = 13 is subtracted from h
h – 13 + 13 = 5 + 13 To solve the equation, use the inverse operation, addition.
h = 18

Question 7.
$$\frac{y}{3}$$ = -6 ______
$$\frac{y}{3}$$ = -6 y is divided by 3
$$\frac{y}{3}$$ * 3 = -6 * 3 To solve the equation, use the inverse operation, multiplication.
y = -18

Question 8.
b + 9 = 21 _________
b + 9 = 21 9 is added to b
b + 9 – 9 = To solve the equation, use the inverse operation, subtraction.
b = 12

Question 9.
c – 8 = -8 ________________
c – 8 = 8 8 is subtracted from c
c – 8 + 8 = -8 + 8 To solve the equation, use the inverse operation, addition
c = 0

Question 10.
3n = -12 _______
3n = -12
n is multiplied by 3
$$\frac{3 n}{3}$$ = $$\frac{-12}{3}$$ To solve the equation, use the inverse operation, division.
n = -4

Question 11.
-16 = m + 7 _______
-16 = m + 7 7 is added to m

-16 – 7 = m + 7 To solve the equation, use the inverse operation, subtraction.
m = -23

Question 12.
$$\frac{t}{-5}$$ = -5 ____
$$\frac{t}{-5}$$ = -5
As we can see t is divided by (-5), so to solve the equation, we use the inverse operation: muLtiplication.
$$\frac{t}{-5}$$ . (-5) = (-5) . (-5)
t = 25
