Question

complete the ratio table.
15 17
30 34
45
68
85

Explanation:

Step1: Find the ratio factor

The ratio of the first row is $\frac{15}{17}$, so each left value is $\frac{15}{17}$ of the right value, or each right value is $\frac{17}{15}$ of the left value.

Step2: Calculate 3rd row right value

Multiply left value by $\frac{17}{15}$: $45 \times \frac{17}{15} = 51$

Step3: Calculate 4th row left value

Multiply right value by $\frac{15}{17}$: $68 \times \frac{15}{17} = 60$

Step4: Calculate 5th row left value

Multiply right value by $\frac{15}{17}$: $85 \times \frac{15}{17} = 75$

Answer:

The completed table values are (from top to bottom of empty cells): 51, 60, 75

15	17
45	51
60	68
75	85
