Answer 1

10 2/5 * (5/13 - 1 9/26)=-10
1)5/13-1 9/26=10/26-35/26=-25/26
2)10 2/5*(-25/26)=-52/5*25/26=-10

Answer 2

10 + 2/5 * (5/13 + 1 + 9/26)

First, let's simplify the expression inside the parentheses: 5/13 + 1 + 9/26 To add these fractions, we need to find a common denominator. The least common multiple of 13 and 26 is 26. So, we can rewrite 5/13 as 10/26. Now we can add the fractions: 10/26 + 26/26 + 9/26 = (10 + 26 + 9)/26 = 45/26

Now, we can substitute this back into the original expression: 10 + 2/5 * 45/26

To multiply the mixed number 2/5 by the fraction 45/26, we first need to convert 2/5 to an improper fraction: 2/5 = 10/26

Now we can multiply the fractions: 10 + 10/26 * 45/26 = 10 + (10 * 45)/(26 * 26) = 10 + 450/676 = 10 + 225/338

So, the final answer is: 10 + 225/338
