Question

-1/3+-7/4
help plssssssssssssssssssssssssssss

Answer 1

`- (25)/(12)`

Explanation:

Hi there! This is something easy.

We have the fractions:
`- (1 )/(3) + - (7)/(4)`

Take the LCM of the denominators, then, divide the LCM obtained by each denominator and multiply the results by their numerators. ( always observe and mind the mathematical signs especially the minus sign).

`( - 4 + ( - 21))/(12)`

→
`( - 4 - 21)/(12) = - (25)/(12)`

Therefore:
`- (25)/(12)` is the final answer.

I hope this helps.

Answer 2

`-( 1)/(3) + ( ( - 7)/(4) ) = \\ - (1)/(3) - (7)/(4 ) = \\ the \: lcm \: of \: 3 \:and \: 4 \: is \: 12 \\ \\ ( - 4 - 21)/(12 ) = - (25)/(12)`
