-1/2+ 7/8- 1/10 Hint: rational numbers

ki77a [65]

After solving $-\frac{1}{2}+\frac{7}{8}-\frac{1}{10}\\$ we get $\frac{11}{40}$

Step-by-step explanation:

We need to solve the following expression:

$-\frac{1}{2}+\frac{7}{8}-\frac{1}{10}\\$

Solving the above expression we need to find the LCM of denominators: 2,8,10

The LCM of 2,8,10 is 40

$-\frac{1}{2}+\frac{7}{8}-\frac{1}{10}\\=\frac{-1*20+7*5-1*4}{40}\\=\frac{-20+35-4}{40}\\=\frac{11}{40}$

So, after solving $-\frac{1}{2}+\frac{7}{8}-\frac{1}{10}\\$ we get $\frac{11}{40}$
