Answer:
A.)D23
Step-by-step explanation:
No there are two pints in a quart
C. Divide the numerator by the denominator.
a cheap way to go about it is, let's do away with the denominators, and we'll do so by simply multiplying both sides by the the LCD of all fractions, in this case, that'd be "ab", so we multiply both sides by "ab".

First either add or subtract the number in the parenthesis (3^2-4) which equals to 5
90/[10+5) add the number in the parenthesis again (always do the parenthesis first) [10+5]= 15.
lastly divide 90/15 which equals to 6
always remember (PEMDAS)
