Answer 3

To solve the expression 6 7/12 + (5 3/40 - 4 8/15), we need to perform the operations in the parentheses first, and then add the result to 6 7/12.

Let's simplify the expression step by step:

Step 1: Solve the expression inside the parentheses.

5 3/40 - 4 8/15 To subtract mixed numbers, we need to convert them to improper fractions.

5 3/40 = (5 * 40 + 3)/40 = 203/40 4 8/15 = (4 * 15 + 8)/15 = 68/15

Now we have: 203/40 - 68/15

To subtract fractions, we need a common denominator. In this case, the least common multiple (LCM) of 40 and 15 is 120.

Now we can rewrite the expression with a common denominator:

(203/40) - (68/15) = (203 * 3)/(40 * 3) - (68 * 8)/(15 * 8) = 609/120 - 544/120 = (609 - 544)/120 = 65/120

Step 2: Add the result from the parentheses to 6 7/12.

6 7/12 + (65/120)

To add mixed numbers, we need to convert them to improper fractions.

6 7/12 = (6 * 12 + 7)/12 = 79/12

Now we have: 79/12 + 65/120

To add fractions, we need a common denominator. In this case, the least common multiple (LCM) of 12 and 120 is 120.

Now we can rewrite the expression with a common denominator:

(79/12) + (65/120) = (79 * 10)/(12 * 10) + (65 * 1)/(120 * 1) = 790/120 + 65/120 = (790 + 65)/120 = 855/120

The fraction 855/120 can be simplified by dividing both the numerator and denominator by their greatest common divisor (GCD), which is 15.

855/120 = (855 ÷ 15)/(120 ÷ 15) = 57/8

Therefore, the simplified value of the expression 6 7/12 + (5 3/40 - 4 8/15) is 57/8.
