<em />
<em>Step-by-step explanation:</em>
<u>-Question A-</u>
1) Rephrase the problem to look like this:
3/7*28/15*5/14 <-- when dividing fractions you actually multiply by the reciprocal (opposite)
2) Multiply across the above phrase:
420/1470
3) Simplify your fraction:
2/7
There is nothing else to be done with 2/7 and thus it is your final answer.

<u>-Question B-</u>
1) Get the denominator of all 3 fractions to the same Least Common Denominator (48):
42/48 + 3/48 - 4/48
2) Do the arithmetic in the phrase above:
41/48
41/48 cannot be simplified and thus is your final answer
