Question

compare the ratio.7:9 and 10:12

Answer 1

Solution -

7:9 = 7/9 = 7×4/9×4= 28/36

10:12 = 10/12 = 10×3/12×3 = 30/36

As, 28/36 < 30/36

Therefore,

7:9 < 10:12

Explaination -

Here, at first we need to convert the given ratio into fraction.

After converting into fraction, we found that both the dinominators are different from each other. So, the second step is to make their dinominators equal.

After making their dinominators equal we found that 28/36 is smaller than 30/36...

Therefore, 7:9 is smaller than 10:12 or 10:12 is greater than 7:9

Answer 2

$\frac{7}{9} = \frac{7 \times 4}{9 \times 4} = \frac{28}{36} \\ \\ \frac{10}{12} = \frac{10 \times 3}{12 \times 3} = \frac{30}{36} \\ \\ \frac{30}{36} > \frac{28}{36} \\ \\ \frac{7}{9} < \frac{10}{12}$
