The improper fraction 10 / 9 can be written as mixed number.
9 goes into 10 1 time with 1 left over. The first 1 is the whole number, and the second 1 is the numerator. The mixed number is 1 1/9.

5 / 7 = ? / 21
You have to multiply the denominator 7 by 3 to get 21, so you multiply the numerator 5 by 3 and the new numerator is 15. The new fraction 15 / 21.
