Answer 2

To calculate the expression {4 + 2 7/15} * {10 - 8 16/23}, follow these steps:

Step 1: Convert mixed numbers to improper fractions: 4 + 2 7/15 = 4 + (2 * 15/15 + 7/15) = 4 + 30/15 + 7/15 = 4 + 37/15

8 16/23 = (8 * 23/23 + 16/23) = 184/23 + 16/23 = 200/23

Step 2: Calculate the expressions inside the braces: {4 + 37/15} = (4 * 15/15 + 37/15) = 60/15 + 37/15 = 97/15

{10 - 200/23} = (10 * 23/23 - 200/23) = 230/23 - 200/23 = 30/23

Step 3: Multiply the results from step 2: (97/15) * (30/23)

Step 4: Multiply the numerators together and the denominators together: (97 * 30) / (15 * 23)

Step 5: Calculate the numerator and denominator separately: Numerator = 2910 Denominator = 345

Step 6: Simplify the fraction, if possible: 2910/345 = 870/115

Step 7: Further simplify the fraction by dividing both the numerator and denominator by their greatest common divisor, which is 5: (870 ÷ 5) / (115 ÷ 5) = 174/23

So, the result of the expression {4 + 2 7/15} * {10 - 8 16/23} is equal to 174/23.
