Question

complete the ratio table.
19 18
□ 36
57 54
□ 72
□ 90

Explanation:

Step1: Find the scaling factor

First, identify how the right column values scale. From 18 to 36: $\frac{36}{18}=2$

Step2: Calculate first missing value

Multiply 19 by the scaling factor 2: $19 \times 2 = 38$

Step3: Verify the ratio consistency

Check the third row: $\frac{57}{19}=3$, $\frac{54}{18}=3$, so the ratio is $19:18$ (or $\frac{19}{18}$)

Step4: Calculate second missing value

Find the scaling factor for 72: $\frac{72}{18}=4$. Multiply 19 by 4: $19 \times 4 = 76$

Step5: Calculate third missing value

Find the scaling factor for 90: $\frac{90}{18}=5$. Multiply 19 by 5: $19 \times 5 = 95$

Answer:

The completed ratio table is:

19	18
57	54
76	72
95	90

The missing values (top to bottom) are 38, 76, 95.
