Question

7/10 divided by -2/5

Answer 1

Answer:

$-1\frac{3}{4}$

Step-by-step explanation:

$\frac{7}{10} \div\frac{-2}{5}$

Use KCF (Keep, Change, Flip)

$\frac{7}{10} \times\frac{-5}{2}$

Positive times a negative equals a negative:

$7\times5=35$

$2\times10=20$

$=\frac{-35}{20}$

Reduce

$35\div5=7$

$20\div5=4$

$=\frac{-7}{4}$

Convert into a mixed number

$\frac{-7}{4} =-1\frac{3}{4}$

$=-1\frac{3}{4}$

Hope this helps

Answer 2

$\frac{7}{10}:\frac{-2}{5}=\frac{7}{10}*\frac{-5}{2}=\frac{-35^{(5}}{20}= \frac{-7}{4}$
