-1-2(9/14)

Solution

- 1 - 2 (\frac{9}{14})

- \frac{16}{7}

Solution steps

- 1 - 2 (\frac{9}{14})

Follow the PEMDAS order of operations

Multiply and divide (left to right)

2 (\frac{9}{14}) : \frac{9}{7}

2 (\frac{9}{14})

Apply rule:

(a) = a

(\frac{9}{14}) = \frac{9}{14}

= 2 \cdot \frac{9}{14}

2 \cdot \frac{9}{14} = \frac{9}{7}

2 \cdot \frac{9}{14}

Convert element to fraction:

2 = \frac{2}{1}

= \frac{2}{1} \cdot \frac{9}{14}

Apply the fraction rule:

\frac{a}{b} \cdot \frac{c}{d} = \frac{a \cdot c}{b \cdot d}

= \frac{2 \cdot 9}{1 \cdot 14}

\frac{2 \cdot 9}{1 \cdot 14} = \frac{9}{7}

\frac{2 \cdot 9}{1 \cdot 14}

Multiply the numbers:

1 \cdot 14 = 14

= \frac{2 \cdot 9}{14}

Factor the number:

14 = 2 \cdot 7

= \frac{2 \cdot 9}{2 \cdot 7}

Cancel the common factor:

2

= \frac{9}{7}

= \frac{9}{7}

= \frac{9}{7}

= - 1 - \frac{9}{7}

Add and subtract (left to right)

- 1 - \frac{9}{7} : - \frac{16}{7}

- 1 - \frac{9}{7}

- 1 - \frac{9}{7} = - \frac{16}{7}

= - \frac{16}{7}

= - \frac{16}{7}

\frac{6 ^{5}}{2 ^{5} \times 3 ^{3}}

670 \div 180 \times 20 \div 41

6 \times (2 \frac{1}{6} - 1 \frac{3}{4})

2 \cdot 2 \cdot (- 1) - 3 - 3

(2^{2} 3^{2})^{2}
