Question

1. Which ratio is larger in the following pairs (i) 3 : 4 and 5: 7 ​

Answer 1

$\sf \underline{Answer}$

To compare the size of two ratios, we write it as a fraction and find out the LCM of the denominators:-

LCM of 4 and 7 = 28

__________________________

1st ratio:-

$\sf \: \frac{3 \times 7}{4 \times 7} = \frac{21}{28}$

2nd ratio:-

$\sf \: \frac{5 \times 4}{7 \times 4} = \frac{20}{28}$

________________________

Therefore the 1st original ratio of $\sf \frac{3}{4}$ is larger than the 2nd ratio.
