Question

Add 17/20+7/201: 1 1/52: 1 5/203: 2 1/54: 1 3/20

Answer 1

Since both fractions have the same denominator we just have to add the numerators:

`(17)/(20)+(7)/(20)=(17+7)/(20)=(24)/(20)`

This result can be simplified by dividing both numerator and denominator by 4:

`(24)/(20)=(6)/(5)`

And finally, we can write this as a mixed number (like in the options). We can do that very easily with a diagram:

So the result written as a mixed number is:

`(6)/(5)=1(1)/(5)`

The correct answer is option 1
