10-(3/4+2/8)

10 - (\frac{3}{4} + \frac{2}{8})

9

Solution steps

10 - (\frac{3}{4} + \frac{2}{8})

\frac{2}{8} = \frac{1}{4}

Cancel the common factor:

2

\frac{1}{4}

= 10 - (\frac{3}{4} + \frac{1}{4})

Follow the PEMDAS order of operations

Calculate within parentheses

(\frac{3}{4} + \frac{1}{4}) : 1

\frac{3}{4} + \frac{1}{4}

\frac{3}{4} + \frac{1}{4} = 1

\frac{3}{4} + \frac{1}{4}

Apply rule

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{3 + 1}{4}

Add the numbers:

3 + 1 = 4

= \frac{4}{4}

Apply rule

\frac{a}{a} = 1

= 1

= 1

= 10 - 1

Add and subtract (left to right)

10 - 1 : 9

10 - 1

10 - 1 = 9

= 9

= 9
