Rewrite each fraction with a denominator of 10 7/2 3/5

Vaselesa [24]

Answer:

$\frac{7}{2}=\frac{35}{10}$

$\frac{3}{5}=\frac{6}{10}$

Step-by-step explanation:

Given the fraction

$\frac{7}{2}$

Multiplying numerator and denominator by 5

$\frac{7}{2}\times \frac{5}{5}$

$=\frac{35}{10}$

Therefore,

$\frac{7}{2}=\frac{35}{10}$

Similarly,

Given the fraction

$\frac{3}{5}$

Multiplying numerator and denominator by 2

$\:\frac{3}{5}\times \:\frac{2}{2}$

$\frac{3}{5}\times \:\frac{2}{2}=\frac{6}{10}$

Therefore,

$\frac{3}{5}=\frac{6}{10}$
