Answer 2

To solve the expression, let's break it down step by step:

1. Simplify the first term, U+3/8: U is an unknown value, so we cannot simplify this further. We'll keep it as it is.

2. Simplify the second term, 7/20 - 7/8: To subtract fractions, we need a common denominator. The least common multiple (LCM) of 20 and 8 is 40. So, let's convert the fractions to have a denominator of 40: 7/20 = (7 * 2)/(20 * 2) = 14/40 7/8 = (7 * 5)/(8 * 5) = 35/40

   Now we can subtract the fractions: 14/40 - 35/40 = (14 - 35)/40 = -21/40

3. Combine the simplified terms: U + (-21/40) = U - 21/40

Therefore, the simplified expression is U - 21/40, which cannot be further simplified without more information about the value of U.
