Question

A warehouse has 12 and nine-tenths meters of tape in one area of the building, and eight and three-fifths meters of tape in another part. How much tape does the warehouse have in all?

Answer 1

To solve this problem, we will add two mixed numbers, with the fractional parts having unlike denominators.

`12(9)/(10)+8(3)/(5)=12(9)/(10)+8(6)/(10)=20(15)/(10)=21(5)/(10)=21(1)/(2)`

Then the answer is the mixed number 21 1/2
