For every liter she used, she drove 8 kilometers. In this problem you are finding the unit rate. In order to do this you divide 48 (kilometers) by 6 (liters of gasoline).
48 Divided by 6 equals to 6 Kilometers
—- —-
6 Divided by 6 equals to 1 Liter
For the second question you divide the liter by 6. Amelia used 0.1666 liters of gasoline per kilometer. 0.1666 is equivalent to 1/6.
Step-by-step explanation:
Similar figures have same ratio of corresponding sides.
Set up ratios and solve for x.
#1
- x / 54 = 6 / 36
- x / 54 = 1/6
- x = 54/6
- x = 9
#2
- x / 4 = 99 / 11
- x / 4 = 9
- x = 4*9
- x = 36
#3
- x / 10 = 6 / 60
- x / 10 = 1/6
- x = 10/6
- x = 5/3
#4
- x / 4 = 28 / 7
- x / 4 = 4
- x = 4*4
- x = 16
Answer:
8
Step-by-step explanation:
8^2=64 8*5=40 64-40=24
