<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></u>
<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

Adam is 9 years old and Bob is 6. Twice Bob’s age is 12, three years younger than that is 9. If Adam is 9 now then in five years, Adam will be 14, which is 8 more than 6.
Use foil which is a lazy way to remember theh distributive property
goes like this
multiply
First terms
Outer terms
Inner terms
Last terms
and add them all toegethe
so
(x+2)(x+2)
First: x times x or x²
Outer: x times 2 or 2x
Inner: 2 times x or 2x
Last: 2 times 2 or 4
add them toegether
x²+2x+2x+4=
x²+4x+4
