To add fractions, you first have to make sure they have a common denominator.

7/10 + 1/10 + 1/10 = (7 + 1 + 1)/10 = 9/10

Next,

14/15 + 3/2 + 16/15 + 1/2

We can convert 3/2 to an equivalent fraction with a denominator of 15 by multiplying the numerator and denominator by 15:

3/2 = 45/30

Now, we can add the fractions:

14/15 + 45/30 + 16/15 + 1/2

To have a common denominator of 30, we need to multiply the numerator and denominator of 14/15 and 16/15 by 2:

14/15 = 28/30
16/15 = 32/30

Now we have:

28/30 + 45/30 + 32/30 + 15/30 = (28 + 45 + 32 + 15)/30 = 120/30 = 4

So, 14/15 + 3/2 + 16/15 + 1/2 = 4.
