Question

Which expression does NOT equal 4/5?

4 x 1/5
2 + 2/5
1/5 + 1/5 + 1/5 + 1/5
2 x 2/5

Answer 1

4 x 1/5 is 4/5 so it is not that one. 1/5+1/5+1/5+1/5 equals 4/5 so it is not that one. 2 x 2/5 is 4/5 so it is not that one.

2+2/5 is 12/5 so this expression does not equal 4/5

Answer 2

2 + 2/5 is not equal to 4/5

Explanation:

`4*(1)/(5) =(4)/(5)`

`2 + 2/5 = 2 + (2)/(5)=(10)/(5) +(2)/(5) =(12)/(5)`

`(1)/(5)+ (1)/(5)+ (1)/(5)+ (1)/(5)=(4)/(5)`

`2*(2)/(5) =(2*2)/(5) =(4)/(5)`
