1112pounds

Explanation:

He bought 13pounds of turkey and 34pounds of beef. We need to add the two numbers together to get how many pounds of MEAT he bought in total.

turkey + beef = total amount of meat he bought

p= pound

13p+34p

Now in order to add it together we have to find a common denominator for two fractions.

Therefore we do 3×4 which is 12 so the common denominator is 12.

For the first fraction13 we need to get 12 as denominator so the new numerator is unknown.

13×x12

3x=12

x=4

The new fraction is412, it is the same as we multiplied the whole fraction(numerator and denominator) with 4.

For the second fraction we do the same thing.

34=x12

4x=12×3

4x=36

x=364=9

The new fraction is 912. This is also like multiplying the whole fraction with 3.

At the end, we just add those two fractions, numerator with numerator and since the denominator is the same, it stays the same.

412p+912p=1312p=1112p
