2) 14/25
3) 2/9
4) 3/21
6)11/24

Answer 2

To solve the given expression:

2/9 + 7/45 - 2/5 + 4/25 + 1/3 - 1/9 - 10/21 - 1/3 + 4/9 - 7/8 - 5/12

Let's simplify it step by step:

Step 1: Find a common denominator for all the fractions. The common denominator for 9, 45, 5, 25, 3, 9, 21, 3, 9, 8, and 12 is 360.

Step 2: Convert all the fractions to have a denominator of 360.

2/9 = 80/360 7/45 = 28/180 2/5 = 144/360 4/25 = 64/360 1/3 = 120/360 1/9 = 40/360 10/21 = 200/360 1/3 = 120/360 4/9 = 160/360 7/8 = 315/360 5/12 = 150/360

Step 3: Add and subtract the fractions.

80/360 + 28/360 - 144/360 + 64/360 + 120/360 - 40/360 - 200/360 - 120/360 + 160/360 - 315/360 - 150/360

Step 4: Combine like terms.

(80 + 28 - 144 + 64 + 120 - 40 - 200 - 120 + 160 - 315 - 150)/360

Step 5: Calculate the numerator.

(33)/360

Step 6: Simplify the fraction.

1/10

Therefore, the simplified value of the given expression is 1/10.
