Question:
Find the given percent or fraction of the number.
14. 30% of 256 15. 25% of 2,048
16. 2/3 of 24 17. 5/6 of 90
How do i figure those out? I don't whant the answer I wanna know how to sovle them.
You turn the percent into a decimal by moving the decimal point two places to the left. Then multiply. For instance -- 30% = 0.3. So 30% of 256 = 0.3 * 256.
You turn the fraction into a decimal by dividing the numerator by the denominator and then multiplying.
If you post your answers, we'll be glad to check them.
so for 14. 30% of 256 is...76.8
15. 25% of 2,048 is....512
16. 2/3 of 24 is...16
17. 5/6 of 90 is...75

Write each comparison as a percent.
18. 55 out of 100
19. 13 out of 39
20. 2.5 out of 10
21. 5 out of 100
sorry to throw more at u... i bet thses are easy questions for u thought because they are 7th grade questions...
It might be easiest to first write your comparison as a fraction..55/100, 13/39, etc. Then you put you denominator (bottom number) on the outside of a division problem and it will give you the decimal. 55 divided by 100
13 divided by 39
2.5 divided by 10, etc.
Good luck!
The word "of" in a math problem almost always indicates that you'll need to multiply:
14. 30% of 256 = .30 x 256 = ?
15. 25% of 2,048 = .25 x 2048 = ?

16. 2/3 of 24 = 2/3 x 24/1 = ?
17. 5/6 of 90 = 5/6 x 90/1 = ?

Good for you!
=)
13 out of 39 = 13/39
Divide 39 into 13
2.5 out of 10 = 2.5/10
Divide 10 into 2.5
