7 - 112 \cdot \frac{6}{50}

- \frac{161}{25}

Solution steps

7 - 112 \cdot \frac{6}{50}

\frac{6}{50} = \frac{3}{25}

Cancel the common factor:

2

\frac{3}{25}

= 7 - 112 \cdot \frac{3}{25}

Follow the PEMDAS order of operations

Multiply and divide (left to right)

112 \cdot \frac{3}{25} : \frac{336}{25}

112 \cdot \frac{3}{25}

Convert element to fraction:

112 = \frac{112}{1}

= \frac{112}{1} \cdot \frac{3}{25}

Apply the fraction rule:

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

= \frac{112 \cdot 3}{1 \cdot 25}

Multiply the numbers:

112 \cdot 3 = 336

= \frac{336}{1 \cdot 25}

Multiply the numbers:

1 \cdot 25 = 25

= \frac{336}{25}

= 7 - \frac{336}{25}

Add and subtract (left to right)

7 - \frac{336}{25} : - \frac{161}{25}

7 - \frac{336}{25}

7 - \frac{336}{25} = - \frac{161}{25}

7 - \frac{336}{25}

Convert element to fraction:

7 = \frac{7 \cdot 25}{25}

= \frac{7 \cdot 25}{25} - \frac{336}{25}

Since the denominators are equal, combine the fractions:

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

= \frac{7 \cdot 25 - 336}{25}

7 \cdot 25 - 336 = - 161

7 \cdot 25 - 336

Multiply the numbers:

7 \cdot 25 = 175

= 175 - 336

Subtract the numbers:

175 - 336 = - 161

= - 161

= \frac{- 161}{25}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{161}{25}

= - \frac{161}{25}

= - \frac{161}{25}

- 7^{2} - 4 (- 7) + 8

\frac{1}{2} (3) + 1

7 - (- 3)^{2}

11 \times 4 + 11 \times 3

4 \cdot 1 6^{2}
