B. His answer is correct because 4th plus one equals 13 and 15 plus 10 equals 25
C. His answer is not correct, because the same can not be less than either attend
D. his answer is correct because all the fractions are less than one​

Answer 1

Option C. His answer is not correct, because the same can not be less than either attend

Explanation:

we have

`(12)/(15)+(1)/(10) =(13)/(25)`

we know that

`(12)/(15)=0.8`

`(1)/(10)=0.10`

`(13)/(25)=0.52`

substitute

`0.80+0.10=0.52` ----> is not true

therefore

His answer is not correct, because the same can not be less than either attend
