Question

Find −9 7/10−(−4 3/5) . Write your answer as a mixed number in simplest form.

Answer 1

The answer is -5 1/10

Answer 2

- 5
`(1)/(10)`

Explanation:

since there is nothing to be solved inside the parentheses you remove them-- instead of keeping the subtraction sign and the negative sign you change it to an addition *positive* sign

-9
`(7)/(10)` + 4
`(3)/(5)`

Next changing the denominator 10

-9
`(7)/(10)` + 4
`(6)/(10)` ( 5 x 2 = 10 , 2 x 3 = 6 , changing the numerator to 6)

now you can solve the problem (subtract in this case),

( - [] + [] = - )

7 - 6 = 1

9 - 4 = 5

10 stays the same

this should get you

= - 5
`(1)/(10)`

-5 1/10 is the answer as a mixed number in the simplest form

(decimal = -5.1

(improper fraction = - 51/10
