=91/15*15/13=7

Answer 2

Calculation

The given expression is: (17.6 ÷ 4 5/7 + 2 1/3) * 1 2/13

Let's break it down step by step.

Step 1: Convert Mixed Numbers to Improper Fractions

First, we convert the mixed numbers to improper fractions: - 17.6 = 17 3/5 - 4 5/7 = (4 * 7 + 5) / 7 = 33/7 - 2 1/3 = (2 * 3 + 1) / 3 = 7/3 - 1 2/13 = (1 * 13 + 2) / 13 = 15/13

So, the expression becomes: (17 3/5 ÷ 33/7 + 7/3) * 15/13

Step 2: Perform Division and Addition

Next, we perform the division and addition: - 17 3/5 ÷ 33/7 = (88/5) ÷ (33/7) = (88/5) * (7/33) = 616/165 - 616/165 + 7/3 = (616/165) + (385/165) = 1001/165

Step 3: Perform Multiplication

Finally, we perform the multiplication: - (1001/165) * (15/13) = 15015/2145

So, the result of the given expression is 15015/2145.

Conclusion

The result of the given expression (17.6 ÷ 4 5/7 + 2 1/3) * 1 2/13 is 15015/2145.
