ratios 7 : 8 and 5 : 7

To find:

Compare the given ratios

Solution:

7 : 8 and 5 : 7

$= > \dfrac{7}{8} \: and \: \dfrac{5}{7}$

LCM of 8 and 7 is 56.

Make the denominator of each fraction equal to 56

$= > \dfrac{7}{8} \times \dfrac{7}{7} = \dfrac{49}{56}$

$= > \dfrac{5}{7} \times \dfrac{8}{8} = \dfrac{40}{56}$

we can see that 49 is greater than 40

$= > \dfrac{49}{56} > \dfrac{40}{56}$

$= > \dfrac{7}{8} > \dfrac{5}{7}$

Hence, 7/8 is greater than 5/7
