How do you turn fractions into mixed numbers?

Multiply the whole number times the fraction's denominator, and add the result to the existing numerator.

Examples :

2 3/7

= [ (2x7) + 3] /7 = 17/7

3 and 7/10

= (10 * 3 + 7)/10 = 37/10

(Multiply fraction's denominator times whole number, add that product to fraction's numerator, and place over original fraction's denominator. )
