Solution

- \frac{2}{7} \cdot 1 + 1

\frac{5}{7}

Solution steps

- \frac{2}{7} \cdot 1 + 1

Follow the PEMDAS order of operations

Multiply and divide (left to right)

- \frac{2}{7} \cdot 1 : - \frac{2}{7}

- \frac{2}{7} \cdot 1

- \frac{2}{7} \cdot 1 = - \frac{2}{7}

= - \frac{2}{7}

= - \frac{2}{7} + 1

Add and subtract (left to right)

- \frac{2}{7} + 1 : \frac{5}{7}

- \frac{2}{7} + 1

- \frac{2}{7} + 1 = \frac{5}{7}

- \frac{2}{7} + 1

Convert element to fraction:

1 = \frac{1 \cdot 7}{7}

= \frac{1 \cdot 7}{7} - \frac{2}{7}

Since the denominators are equal, combine the fractions:

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

= \frac{1 \cdot 7 - 2}{7}

1 \cdot 7 - 2 = 5

1 \cdot 7 - 2

Multiply the numbers:

1 \cdot 7 = 7

= 7 - 2

Subtract the numbers:

7 - 2 = 5

= 5

= \frac{5}{7}

= \frac{5}{7}

= \frac{5}{7}

5^{3} - 125

- 3 (1) + 9

20 \times 7^{0}

(3 + 5 + 22) - 3 - 6

\frac{2}{5} - (\frac{3}{9} - \frac{2}{4})
