Final answer:
To add the given expression, first simplify each fraction, find a common denominator, add the numerators, and then simplify the resulting fraction. The simplified result is 16 1/3.
Step-by-step explanation:
To add the given expression, we first need to simplify each fraction.
The first fraction is 15(3)/10, which can be simplified to 45/10.
The second fraction is 25(5)/12, which can be simplified to 125/12.
Now, we can add all the terms together:
45/10 + 15 + 125/12
To add these fractions, we need a common denominator. The denominator of 10 can be multiplied by 12 to get a common denominator of 120. So, the expression becomes:
45/10 + 15/1 + 125/12
Converting all the fractions to have a denominator of 120:
540/120 + 180/120 + 1250/120
Adding the numerators:
(540 + 180 + 1250)/120 = 1970/120
Simplifying the fraction:
1970/120 = 98/6 = 16 1/3
So, the simplified result of the addition is 16 1/3.
