Answer 2

To simplify the given expressions, let's combine like terms and perform any necessary calculations.

A) 2/7x - 4/9y - 9.2m + 15m

Step 1: Combine the "m" terms. 15m - 9.2m = 5.8m

The simplified expression becomes: 2/7x - 4/9y + 5.8m

B) 0.5a - 2/3b - 2/5a - 1/3b

Step 1: Combine the "a" terms and "b" terms separately. 0.5a - 2/5a = (0.5 - 2/5)a = (0.5 * 5/5 - 2/5)a = (3/5)a -2/3b - 1/3b = (-2/3 - 1/3)b = (-3/3)b = -b

Step 2: Combine the simplified "a" and "b" terms. (3/5)a - b

The simplified expression becomes: (3/5)a - b
