2. What's the sum of 2/5 and 2/4?

А. 10

В. 20

C. 64

D. 120

18/20

Step-by-step explanation:

In order to answer, the denominators need to be the same.

The denominators are 4 and 5. we know that 4 times 5 = 20.

Then, we multiply both numerators by the same number that we multiplied the denominator.

2 times 5 = 10 and 2 times 4 = 8.

Now, we add the new numerators together.

10 + 8 = 18

Finally, we "make" the final fraction.

18/20
