There are two ways to do this.
The first way is to convert both numbers to decimals, then use a calculator.
Since 6 is already in decimal form, we need to convert 5/8 to decimal.
5/8 in decimal form is 0.625.
Using a calculator 6 / 0.625 = 9.6
The second way is convert both to fractions.
6 = 6/1
6/1 divides by 5/8 is equal to multiplying 6/1 by the reciprocal of 5/8.
6 times 8/5 is 48/5. The answer is the same.
