1) 28 / 100 x 750 = 210
2) 100 /55 x 49.5 = 90
3) 70 / 100 x 300 = 210
4) 16 / 48 x 100% = 33.3%
5) 145/ 100 x 120 = 174

1. Estimate so 28% is almost 30% so .3(750) = 225
2. 55% of x = 49.5
.55(x) = 49.5 Divide both sides by .55
x = 49.5/.55 = 90
3. 70% of 300
.7(300) = 210
4. x% of 48 is 16
x(48) = 16 Divide both sides by 48
x = 16/48 = 1/3 = .333 = 33.3%
5. 145% of 120
1.45(120) = x
x = 174

750 * 28%= 750 * .28= 210
55% of x=49.5 55/100=x/49.5= 55x=4950
55x/55=4950/55= x=90
70% of 300 = .70 * 300= 210
16 is x% of 48
16/48=x/100= 48x=1600=33.333333...%
145% of 120= 1.45 *120=174
(100%=1)

You equation will want to remember when dealing with percentages is:
(T/A) x 100 = P
T = Total
A = Amount
P = Percentage

1) 10% of 750 is 75 (move decimal place 1 to left)
2x 75 is 150
1% of 750 is 7.5
3x 7.5 = 22.5
150 + 22.5 = 172.5

aren't you supposed to do your own homework. i'm sure your math teacher will check your work anyway, math teachers never accept a single answer without showing your work.
please do it yourself, if you can't do percentages later in life, it will severely hinder your ability to do just about any job.
