I'm preparing for a test, but I don't know how to do this one, my study book and math book do not show an example.

Do I divide by 100? If so, what are the steps in solving a problem like this and what not? THANX! WOULD APPRECIATE IT!!

Why by 1000? Is it because once it's .375, the last #5 is in the thousandths place?

THANX!

37.5%
as % indicates that it is 100.Replace % with 1/100.
So the equation becomes 37.5*1/100.That becomes 375/1000.
as 375 & 1000 are divisible by 5. It becomes 75/200.
But again you can divide it with 5, so it becomes 15/40.
But again you can divide it with 5, so it becomes 3/8.
This you can't divide with any number.So this is the answer.

So the steps are:

37.5%

37.5 * 1/100

37.5 / 100

375 / 1000

75 / 200

15 / 40

3 / 8.

To change a percent to a fraction in this case, since you already have a mixed decimal percent, I would first change it to a decimal by moving the decimal point 2 places to the left (same as dividing by 100) and get

.375

Now this is 375 thousandths, which is why you write 375 over 1000

375/1000

Now reduce. Divide numerator and denominator by 25 and get

15/40 which can be reduced further. Divide both by 5 and get

3/8

You could have divided by 125 but who knows that at first glance? Good luck.

37.5%=.375 because % means divided by 100.
.375=375/1000 divide by 5
75/200 divide by 5 again
15/40 divide by 5 once more
3/8
so 37.5%=3/8

37.5% = .375 = 375/1000 = 15/40 = 3/8
Change the percent to a decimal. Change the decimal to a fraction. Simplify the fraction.

80 one/6 + 22/3=? The denominators for 80 one/6 are 6 and 22/3 is 3. So we would desire to take the consumer-friendly denominator. it would be 6 as 6 could be divided via 6 itself and via 3. now make the denominators equivalent for the two the values. So now the figures ought to be 80 one/6+40 4/6 using fact the denominators are consumer-friendly now, we can simplify as (80 one+40 4)/6 it extremely is a hundred twenty five/6. interior a similar way you're able to do subtractions . For multiplications 80 one/6 * 22/3, merely flow divide. (80 one/3=27.) =27*22/6=ninety 9. to divide you invert and mulitpy so that's 80 one/6 x 3/22 = 243/132

37.5% = (37.5/100) = (375/1000) = (15/40) = (3/8)
