IRINA_888 [86]

Answer:

$\frac{-215}{30}$

Step-by-step explanation:

Given $-2\frac{9}{10} \ and\ -5\frac{4}{15}$

on solving this mixed fraction we get;

$-\frac{29}{10}\ and\ -\frac{64}{15}$

Now adding these fractions by same denominator method.

$-\frac{29\times3}{10\times3} +[-\frac{64\times2}{15\times2} ]\-\frac{87}{30} +[-\frac{128}{30}]\ = -\frac{215}{30}$

Evaluate 81/4-615/32

Kaylis [27]

Answer:33/32

Step-by-step explanation:

81/4 - 615/32

32•4=128 to get a common denominator

Then whatever you do to the top you do to the bottom.

81•32=2,592

Then you would do

615•4=2,460

Now you have

2,592/128 - 2,460/128

Now you subtract

2,592-2460=132

You keep the denominator

132/128 and then simplify by dividing both numbers by four and you get

33/32
