The ratios 84/105 and 128/160 are proportional

<u>Solution:</u>

Given, two ratios are \frac{84}{105} and \frac{128}{160}

We have to give two different reasons to support the answer.

<em><u>Reason 1:</u></em>

Now, we know that, numerators and denominators should be proportional to be two fractions in proportion.

\text { Then, } \frac{84}{128}=0.65625 \text { and } \frac{105}{160}=0.65625

So numerators and denominators are in proportion, then given two fractions are proportion.

<em><u>Reason 2:</u></em>

Now, values of two fractions must be equal:

\rightarrow \frac{84}{105}=\frac{128}{160} \rightarrow 84 \times 160=105 \times 128 \rightarrow 13440=13440

So, values of two fractions are equal, then they are in proportion.

Hence, the given two fractions are in proportion.
