Question

use the interactive tool to find the difference:1- 3/10 .Write the answer as a fraction

Answer 1

The given difference is

$1-\frac{3}{10}$

To find this difference we can use the following property.

$\frac{a}{b}+\frac{c}{d}=\frac{ad+bc}{bd}$

So,

$1-\frac{3}{10}=\frac{1\cdot10-1\cdot3}{1\cdot10}=\frac{10-3}{10}=\frac{7}{10}$

Therefore, the answer is 7/10.
