• fractions -

13 1 / 4 = 13 4 / 20

12 9 / 10 = 12 18 / 20

13 4 / 20 + 12 18 / 20 = 25 22 / 20 =

25 11 / 10 = 25 +10 / 10 + 1 / 10 =

25 + 1 + 1 / 10 = 26 1 / 10

• fractions -

13 1 / 4 = 13 5 / 20

• fractions -

You need to add the weights of both cats together.

First find the common denominator. The smallest number that both 10 and 4 go into is 20.

By multiplying the numerator and the denominator by the same number, we get an equivalent fraction. When we multiply 9/10 by 2/2, we get 18/20. 1/4 multiplied by 5/5 = 5/20

12 18/20 + 13 5/20 = 25 23/20 = 26 3/20

• fractions -

you can add them 12 9/10= 18/20
+ 13 1/4 = 5/20

25 1 3/20 added together so their combined weight is 26 3/20
