Question

complete the ratio table.
31\t98
\t196
93\t294
124\t392
155\t

Explanation:

Step1: Find the ratio

The ratio of first column to second column: $\frac{31}{98} = \frac{93}{294} = \frac{124}{392} = \frac{1}{3.161...}$? No, check multiplier: $98\div31\approx3.161$? Wait, $31\times2=62$, $98\times2=196$. Yes! $31\times2=62$, $98\times2=196$. So ratio is consistent with multiplying by same factor.

Step2: Fill first blank

First blank: $31\times2=62$

Step3: Fill second blank

Second blank: $98\times5=490$ (since $31\times5=155$)

Answer:

62, 490
