Subtract. Write your answer in simplest form. 4 5/8 - 1 1/8=____

Mathematics

4 multiply with 5/8 is 20/8
when the denominator ( the bottom number ) is the same, you simply subtract ( or add ) the numerator ( the top number ) only
so 20/8 - 11/8 is 9/8 (20 - 11 = 9), keeps the denominator as it was :)

Find the percent of each number 0.9 of 1000
trasher [3.6K]

We can use the is/of = p/100 method here. Our given values are 90% and 1000. Think: "What number is 90% of 1000?" Let's plug in our values.

x/1000 = 90/100

Solve for x.

x = (1000)(0.9)

x = 900

So, 900 is 90% of 1000.
