Answer 1

i will medal

Answer 2

Well solve this equation \[\frac{ 3 }{ 8 } = \frac { x }{100}\]. Cross multiply you get 8x = 300. Divide by 8 you get 37.5. So 3/8 = 37.5 and -3/8 = -37.5. I think you can figure out the percent yeah?

Answer 3

um ok

Answer 4

What do you think the percent would be?

Answer 5

um idk i think i divided something wrong

Answer 6

You shouldn't have to divide anything to get the percent. The decimal 37.5 would be the percent aswell.

Answer 7

ok so the decimal would be....would we have to use mathematics to see what that one is?

Answer 8

Yes, you would have to divide 37.5 / 100 or just move the decimal 2 to the right, so .375

Answer 9

ok

Answer 10

What is − 3/8 as a decimal?

Either on paper or on your calculator, divide -3 by 8. Do this before worrying about finding the equivalent as a percentage.

Answer 11

Are you doing this math by hand or with a calculator?

Answer 12

i got 0.375?

Answer 13

calculator

Answer 14

It's a negative fraction so your answer should end up negative by the way.

Answer 15

(3/8) = 0.375, so -(3/8) should be what?

Answer 16

idk sorry

Answer 17

You see that negative sign infront of the second fractions ^?

Answer 18

Just carry it over to the final answer of (3/8)

Answer 19

um...how do we carry it over? sorry i'm terrible at math.

Answer 20

Okay so you see -(3/8), don't worry about the - sign, just divide (3/8) and you get 0.375. Now you didn't do anything with the negative sign and we can't forget it, so just put it in front of 0.375 to get -0.375. Make sense?

Answer 21

ooh ok thank you..so our answer is -0.375? right?

Yes, for the decimal. Now just move the decimal two places to the left to get -37.5%
