Question

-5/4-(-1/6) help please

Answer 1

A way to add fractions that always works is to multiply each numerator by the denominator of the other, then express the sum of products over the product of the denominators.

`(a)/(b)+(c)/(d)=(a)/(b)\cdot(d)/(d)+(c)/(d)\cdot(b)/(b)\\\\=(ad+bc)/(bd)`

Here, you have

`(-5)/(4)-(-1)/(6)=(-5\cdot6-(-1)\cdot4)/(4\cdot6)=(-26)/(24)\\\\=(-13)/(12)=-1(1)/(12)`

The sum is -1 1/12
