Answer 2

To calculate the expression 9 14/15 - 2 1/5 - 4 7/10, you can follow these steps:

Step 1: Convert all the mixed numbers to improper fractions.

• 9 14/15 as an improper fraction is (9 * 15 + 14) / 15 = 139/15.
• 2 1/5 as an improper fraction is (2 * 5 + 1) / 5 = 11/5.
• 4 7/10 as an improper fraction is (4 * 10 + 7) / 10 = 47/10.

Now, the expression becomes:

139/15 - 11/5 - 47/10

Step 2: Find a common denominator for the fractions. The common denominator for 15, 5, and 10 is 30. So, rewrite each fraction with a denominator of 30:

(139/15) * (2/2) = 278/30 (11/5) * (6/6) = 66/30 (47/10) * (3/3) = 141/30

Now, the expression becomes:

(278/30) - (66/30) - (141/30)

Step 3: Subtract the fractions:

(278/30) - (66/30) - (141/30) = (278 - 66 - 141) / 30 = 71/30

So, 9 14/15 - 2 1/5 - 4 7/10 is equal to 71/30.
