Answer 3

Let's simplify each of these expressions step by step:

1. (1 - 3/5) + 2 1/5

First, calculate the subtraction inside the parentheses: 1 - 3/5 = 5/5 - 3/5 = (5 - 3)/5 = 2/5

Now, add 2 1/5 to 2/5: 2 1/5 + 2/5 = (2 + 2 1/5)/5 = (2 + 11/5)/5

Now, find a common denominator for 2 and 11/5, which is 5: (2 * 5/5 + 11/5)/5 = (10/5 + 11/5)/5 = (21/5)/5

Divide 21/5 by 5: (21/5)/5 = (21/5) * (1/5) = 21/25

So, the result is 21/25.

2. (5 - 3/4) - 1 1/4

First, calculate the subtraction inside the parentheses: 5 - 3/4 = 20/4 - 3/4 = (20 - 3)/4 = 17/4

Now, subtract 1 1/4 from 17/4: 17/4 - 1 1/4 = (17/4 - 5/4) = 12/4

Simplify 12/4: 12/4 = 3

So, the result is 3.

3. (5/14 + 9/14) - 1

First, add the fractions inside the parentheses: (5/14 + 9/14) = (5 + 9)/14 = 14/14 = 1

Now, subtract 1 from 1: 1 - 1 = 0

So, the result is 0.
