How do u change

into a decimal? ? if u know pls explain

You basically divide the fraction to get your decimal.

You would divide the top number by the bottom number. 3/10 = .30

When dealing with 10, 100, 1000, etc... you will just move the decimal to the left dependent on the number of zeroes. In this case we start out with 3.0 and move it to the left once to get .30

187.5

Step-by-step explanation: Divide 75 by 12 to get 6.25 then multiply that by 30 to get 187.5.
