To divide fractions, you need to multiply the first fraction by the reciprocal of the second fraction. Therefore, 5/6 divided by 15/1 is equivalent to (5/6) * (1/15) = 5/90, which can be simplified to 1/18.
Multiply the number by the percent in decimal form. Example: 15 percent of 40 would be 40 x .15 = 6. (15 percent of 40 is 6).
To multiply an improper fraction by a whole number you first multiply the numerator by the whole number, then divide the result by the denominator. For example: 8/6 x 15 You do 8x15 = 120 Then you do 120/6 = 20. When writing down, you would do this all in one step, as 8/6 x 15 = 20
