PLEASE HELP ME ! WITH THIS

Answer 1

3/4

Explanation:

8 subtracted by 7 1/4.

8/1 - 7 1/4

7 and 1/4th is a mixed number, so we turn it into an improper fraction. We do that by multiplying the whole number by the denominator, and then adding the numerator to the product.

7 x 4 = 28
Then, we add the numerator, 1. 28+1 = 29.

Finally, we solve the equation.

8/1 - 29/4 =

We need the common denominator, in this case, it's 4.

8/1 - 29/4 = _/4 - _/4

8/1-29/4 = 32/4 - 29/4 (What we do the bottom, we do to the top.)
32/4 - 29/4 = 3/4

Therefore, the answer is 3/4.

Answer 2

let's firstly convert the mixed fraction to an improper fraction.

`\stackrel{mixed}{7(1)/(4)}\implies \cfrac{7\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{29}{4}} \\\\[-0.35em] ~\dotfill\\\\ 8-\cfrac{29}{4}\implies \cfrac{(4)8~~ - ~~(1)29}{\underset{\textit{using this LCD}}{4}}\implies \cfrac{32-29}{4}\implies \cfrac{3}{4}`
