Answer 2

To add these numbers, we need to convert any mixed numbers or fractions into a common format. Let's break down the problem step by step:

7 21/25 can be written as an improper fraction: (7 * 25 + 21)/25 = 196/25 5 2/5 can be written as an improper fraction: (5 * 5 + 2)/5 = 27/5 8 3/5 can be written as an improper fraction: (8 * 5 + 3)/5 = 43/5

Now, let's add up all the fractions:

196/25 + 27/5 + 43/5 + (-1.5) + (-3.7)

To add fractions, we need a common denominator. The least common multiple of 25, 5, and 5 is 25. Let's convert all fractions to have a denominator of 25:

(196/25) + (27/5 * 5/5) + (43/5 * 5/5) + (-1.5 * 25/25) + (-3.7 * 25/25) = (196/25) + (27/25) + (43/25) + (-37.5/25) + (-92.5/25)

Now we can add the fractions together:

= (196 + 27 + 43 - 37.5 - 92.5)/25 = 136/25

So, the result of the addition is 136/25.
