Question

Models for two mixed numbers are shown below which equation shows the sum?

Answer 1

`1(10)/(12)+2(5)/(12)`

we will simply add the whole number part

This will give 3

Since, the denominators are the same, we will just pick one, then add the numerator

`=3(15)/(12)`

But, 15/12 = 1 3/12

`=4(3)/(12)`

But 3/12 can be reduced to give 1/4

`=4(1)/(4)`

Hence, the correct answer is D
