Question

3 2/5-(1 1/3+1 1/4)=

Answer 1

1) 1 1/3 + 1 1/4 = 1 4/12 + 1 3/12 + 2 7/12
2)3 2/5 - 2 7/12 = 3 24/60 - 2 35/60 = 2 84/60 - 2 35/60 = 49/60

Answer 2

To calculate the expression 3 2/5 - (1 1/3 + 1 1/4), follow these steps:

Step 1: Convert the mixed numbers to improper fractions.

• 3 2/5 = (5 * 3 + 2)/5 = 17/5
• 1 1/3 = (3 * 1 + 1)/3 = 4/3
• 1 1/4 = (4 * 1 + 1)/4 = 5/4

Step 2: Perform the operations within the parentheses.

• (1 1/3 + 1 1/4) = (4/3 + 5/4)

To add fractions, you need a common denominator, which in this case is 12. So, rewrite the fractions with a common denominator:

• (4/3 + 5/4) = (16/12 + 15/12)

Step 3: Add the fractions inside the parentheses:

• (16/12 + 15/12) = (31/12)

Step 4: Now, you can subtract 31/12 from 17/5:

• 17/5 - 31/12

To subtract fractions, you also need a common denominator, which in this case is 60. So, rewrite the fractions with a common denominator:

• (17/5) = (204/60)
• (31/12) = (155/60)

Step 5: Subtract the fractions:

• (204/60 - 155/60) = (49/60)

So, the final result is 49/60.
