Question

4 5/12 - 1 1/2 : (2 1/6+8/15)× 1 4/5

Answer 1

1) 2 1/6+8/15=13/6+8/15=65/30+16/30=81/30
2) 1 1/2/81/30=3/2*30/81=5/9
3) 5/9*1 4/5=5/9*9/5=1
4) 4 5/12-1= 3 5/12

Answer 2

To solve the expression, follow these steps:

1. Convert mixed numbers to improper fractions: 4 5/12 = (4 × 12 + 5)/12 = 53/12 1 1/2 = (1 × 2 + 1)/2 = 3/2 2 1/6 = (2 × 6 + 1)/6 = 13/6 1 4/5 = (1 × 5 + 4)/5 = 9/5

2. Simplify the expression inside the parentheses: (13/6 + 8/15) = (65/30 + 16/30) = 81/30 = 9/10

3. Perform multiplication: (9/10 × 9/5) = (9 × 9)/(10 × 5) = 81/50

4. Perform subtraction: 53/12 - 3/2 = (53/12) - (18/12) = 35/12

5. Perform division: 35/12 ÷ 81/50 = (35/12) × (50/81) = (35 × 50)/(12 × 81) = 1750/972

The simplified result is 1750/972.
