1000 X 3/4
This can be done multiple ways. The first way is to convert the fraction to a decimal.
3/4=.75
Now that 3/4 is in decimal form, you can multiply it by 1000.
Since 1000 is a multiple of 10, count the zeros. There are three zeros, so you move the decimal point three places to the right. Your answer is 750.
If you want to stay with fractions, write 3/4 x 1000/1.
Multiply 3 by 1000 and 4 by 1.
You get 3000/4
Next, you divide 3000 by four to change it to a mixed number, your answer is 750.
