2)-8/10

plzz tell me answeerr​

Answer 1

Answer:

$(1)\ -\frac{6}{5}$

Equivalents: -12/10, -18/15, -24/20, - 30/25, -36/30

$(2)\ -\frac{8}{10}$

Equivalents: -4/5, 16/20, -24/30, -32/40, -80/100

Step-by-step explanation:

Given

$(1)\ -\frac{6}{5}$

$(2)\ -\frac{8}{10}$

Required

5 equivalent numbers for each

To do this, we carry out the same operation on the numerator and the denominator of the fraction

$(1)\ -\frac{6}{5}$

Multiply by 2/2

$-\frac{6}{5} * \frac{2}{2} = -\frac{12}{10}$

by 3/3

$-\frac{6}{5} * \frac{3}{3} = -\frac{18}{15}$

by 4/4

$-\frac{6}{5} * \frac{4}{4} = -\frac{24}{20}$

by 5/5

$-\frac{6}{5} * \frac{5}{5} = -\frac{30}{25}$

by 6/6

$-\frac{6}{5} * \frac{6}{6} = -\frac{36}{30}$

$(2)\ -\frac{8}{10}$

Divide by 2/2

$-\frac{8}{10}= -\frac{8/2}{10/2}$

$-\frac{8}{10}= -\frac{4}{5}$

Multiply by 2/2

$-\frac{8}{10} =-\frac{8*2}{10*2}$

$-\frac{8}{10}= -\frac{16}{20}$

Multiply by 3/3

$-\frac{8}{10}= -\frac{8*3}{10*3}$

$-\frac{8}{10} =-\frac{24}{30}$

Multiply by 4/4

$-\frac{8}{10} = -\frac{8*4}{10*4}$

$-\frac{8}{10}= -\frac{32}{40}$

Multiply by 10/10

$-\frac{8}{10}= -\frac{8}{10} * \frac{10}{10}$

$-\frac{8}{10}= -\frac{80}{100}$
