I belive that what you're trying to ask is how to convert 1.5 into a fraction. because 1.5 is already a mixed number.
15/7 = 2 and 1/7
31/15 = 21/15
You divide 15 by 2 -giving you 7 and 1/2
You can not convert .75 into a mixed number. Sorry
To convert a mixed number to a decimal, first change the mixed number to an improper fraction and then divide the numerator by the denominator. The quotient will be the decimal number equal to the original mixed number.Example: 3 4/5 = 15/5 + 4/5 = 19/5 = 3.8
90/15 = 6 which is an integer, not a mixed number.90/15 = 6 which is an integer, not a mixed number.90/15 = 6 which is an integer, not a mixed number.90/15 = 6 which is an integer, not a mixed number.
