12/10 an 15/6 as a mixed number

olga_2 [115]

12/10 = 1 2/10 or 1 1/5

15/6 = 2 3/6 or 2 1/2.

To turn these fractions into mixed numbers you have to see how much times the denominator can go into the numerator and the amount of numbers left over. For 12/10, 10 can go into 12 1 time, so the whole number is 1. There is 2 numbers left over, so the numerator is 2 and you do not have to change the denominator. To simplify, divide the numerator and denominator by the highest number it can be divided to
