# How do you simplify 2 7/10 - 3 7/20?

Sep 11, 2016

You can determine the answer by inspection!!

Note that

$6 \frac{1}{2} - 4 \frac{1}{2} = 2$
(the fractions are the same, so they give 0, work with the whole numbers .

$5 \frac{2}{3} - 2 \frac{2}{3} = 3$

In the example $2 \frac{7}{10} - 3 \frac{7}{10}$ the only difference is that we will end up with $- 1$

Look at the maths:

$2 \frac{7}{10} - 3 \frac{7}{10} = 2 - 3 + \frac{7}{10} - \frac{7}{10}$

=$- 1 + 0$

=$- 1$
