How do I do this 7th grade math?

Question

See, I have about 15 questions to do about 1 type of question. Please help. Thanks.

Directions: Estimate by using fractions:

80% of 37

Can you give me a step-by-step guide on how to do it so I can understand how to do it? Thanks.

Answer 1

80% = 80/100
Reduce to 8/10 = 4/5
Multiply by your number

4/5 (37) = 4(37) / 5 = 148/5 = 29 3/5

Answer 2

80 % equals 80 out of 100, right? So that makes 80% equal to 8/10, which reduces to 4/5.

As a fraction, 37 can be shown as 37/1.

Then you multiply the fractions, which can be shown like this:

4/5 * 37/1 = 4 * 37 / 5*1

This equals 148/5, which equals 29.6, which means 29 and 6/10, which reduces to 29 and 3/5.

So the answer is 29 and 3/5. Hope this helped!

An asterisk (*) is the same as a multiplication sign

Answer 3

80% = 80/100 = 8/10
8/10 = 4/5
4/5 * 37 = 4/5 * 37/1 mutiply the 4 by 37 and the 5 by 1 and you get 148/5 reduce and you get 29 and 3/5 since 3 is more than half of 5 then you round the number up to 30

Answer 4

To figure out what 80% is as a fraction, add a 100 under it to get
80/100 which can be reduced to 4/5. To get an exact answer, you would multiply 4/5*37, but for an estimate, round 37 to the closest number ending in 5 or 0. In this case, it's 35. 4/5*35=28.
You can do that by divided 35/5, which gives you 7, then multiplying that by 4 to get 28. Good luck!!

Answer 5

80% of 37

80%=.80=4/5

4/5 x 37/1=148/5=29 3/5

Answer 6

divide 80 by 100 then multiply by 37
(80/100) = 0.8*37 =29.6 or 29 3/5

Answer 7

80% is the same as 80/100 or .8

therefore to get your answer multiply 37 x .8 = 29.6

Answer 8

You can estimate this as 4/5 of 40 = (40 X 4)/ 5 = 32 (approx)

Answer 9

no. X % divide by 100
37 X 80 / 100

or
80% =80/100= 4/5
find 4/5 of 37

1st way easier and always works.

Answer 10

is/of= %/100...

x/37= 80/100

cross multiply

100x=2960

divide by 100 both sides

x= 29.6
