You need to follow the order of operations acronym PEMDAS
ParentheseExponentMultiplyDivideAddSubtract
do the division in the Parentheses first:-
= (4/5 * 3) 5/8
= 12/5 * 5 / 8
= 12/8
= 1 1/2 <----- answer.
12 + 42 is 54. If you take the numbers apart and add them into tens. 42 because 4 10s and your left with 2 ones. If you take 12 and seperate it into tens you get 1 ten with a remainder of 2. 10 + 10 + 10 + 10 + 10 = 50. 2+2 is 4. Remember that they are the same number so 50 + 4 is 54.
A parallelogram is a figure whose opposite sides are parallel. A trapezoid is never a parallelogram.
