Answer 1

The sum of 1y6m, 3y8m, 2y11m is 8y 1m

Step-by-step explanation:

Given the numbers in year and month

We have to find the sum of  1y6m, 3y8m, 2y11m

i.e 1y6m + 3y 8m+ 2y 11m

year        Month

 1y              6m

 3y              8m

 2y              11m

................................

 6y               25m

we know 1 year=12 months

so 2 year = 24 months

so 25 month=2y 1 m

so 6y 25 m = 6y+2y 1m=8y 1m

Therefore the sum of 1y6m , 3y 8m and 2y 11m is 8y 1m

Answer 2

Sum of 1y 6m,3y 8m,2y 11m is 8y 1m.

Step-by-step explanation:

Given : 1y 6m,3y 8m,2y 11m

To find : What is the sum ?

Solution :

The given numbers are in year and month.

i.e. 1y 6m = 1 year 6 month

3y 8m = 3 year 8 month

2y 11m = 2 year 11 month

Adding year by year and month by month.

1y+3y+2y= 6y

6m+8m+11m=25m

Now, convert 25 month into year

1 year = 12 months

1 month = $\frac{1}{12}$ year

25 month =  2 year + 1 month

So, total number of years = 6+2=8 year and 1 month

Sum of 1y 6m,3y 8m,2y 11m is 8y 1m.
