a) 2 b)1  c)1/3 d)5/4

Step-by-step explanation:

Hi to solve this equation we simply have to replace the variable with the number given, and then isolate the variable.

5 x 2/5 = 10 /5 = 2

5/5= 1

In this case after replacing the number we have to simplify it.

2 (2/3) -1 =

4 /3 -1 =

4/3 -3/3 = 1/3

In this case, to add fractions first we have to multiply the top and bottom numbers of the second fraction by 3, to have the same denominators.  

1/2 + 3/4 =

2/4 +3/4 = 5/4
