math Question?

Question

1. 1 and 1/5 = what percent
2. Identify the rate, base, and amount in this question. Do not solve the exercise
at this point. 150 is 75% of what number?
3. In a shipment of 750 parts, 75 were found to be defective. What percent of the parts were faulty?
4. 6.5% of what number is 325?
5. Estimate the amount - What is 48.3% of 1,500?

Answer 1

1.) 6/5 = 120%
2.) let x=the number
.75x = 150

3.) let x = faulty parts PERCENTAGE
75/750 (10) = x%

NOTE: divide the faulty parts by the total parts (75/750), then multiply that by 10, to get percentage. you should get 10%

4.) let x = the number
.065x = 325

NOTE: divide .065 by each side, and you should get 5000. example below

.065x = 325
(/.065) = (/.065)
x = 5000

5.) If it is mental math (750), if regular math...
724.5 ~ 725

Answer 2

1. change to a decimal 1.2 change to percent 120%
2. This is a little strange, but the base is the unknown, the rate is 75%, and the amount is 150
3. Faulty and defective are the same thing so 75/750 is the answer, or .1 or 10%
4. 325 times .065 or 21.125
5. Estimate about half 750

Answer 3

1- 1 =100 + 1/5= 20% = 120%
2. .75 divided by 3 = 25 X 4 =100
3. 750 divided by 75 =10%
4. 325 divided by 100= 0.065 X 325 = 5000
5 1500 divided by .483 = 74.5

Answer 4

1 20 percent or 120% ( the question is not clear)
2. 150 / 0.75 = 200
3. 75/750 = 10%
4. 325/0.065 = 5000
5. a. Less than 750 more than 700
5 b exact .483*1500 = 724.5
