There are four parts to a quarter so you divide 28 by 4:
28/4=7
and then because you want to know three quarters you just times 7 by 3:
7x3=21
therefore three quarters of 28 is 21
Answer:
D
Step-by-step explanation:
m + 9 can be +ve or -ve or 0.
m can be any number, even lesser than -9 to make it +ve. [-10+9 = -1 = -ve no.]
Or, maybe greater than -9 to make m+9 +ve. [-8 + 9 = 1 = +ve no.]
Or, maybe -9 only so that m+9 is 0
[ -9 + 9 = 0 ]
It can be -ve, +ve and 0 as well.
Flip over the second fraction
2 3/5= 13/5 ( Multiply the whole number with the denominator, 2*5=10 then add the numerator 10+3=13
-3 3/4= -15/4
13/5 * -4/15= -52/75
Answer :-52/75
32+56*45
Remember PEMDAS, so we have to solve the multiplication part of the expression first....
32+2520
Now we solve for the addition
2552
Answer=2552
