Question

complete the ratio table. 129 62 124 387 186 516 248 310

Explanation:

Step1: Find the ratio

Check the ratio of first column to second column: $\frac{129}{62} = 2.0806...$? No, check $\frac{62}{129}$? Wait, $\frac{129}{62} \approx 2.08$, but $\frac{387}{186} = 2.0806...$ same as $\frac{129}{62}$. Wait, 129×2=258? No, 62×2=124 (second row second column). So ratio of first column to second column: $\frac{129}{62} = \frac{x}{124}$. Solve for x: $x = 129×\frac{124}{62} = 129×2 = 258$.

Step2: Find the last value

For the last row: second column is 310. Ratio is 129/62 = x/310. So $x = 129×(310/62) = 129×5 = 645$.

Answer:

258, 645
