Answer 2

To solve the expression 12 : (3 3/8) - (1 1/4) : (15/32), let's simplify step by step:

Step 1: Convert mixed numbers to improper fractions: 3 3/8 = (8 * 3 + 3) / 8 = 27/8 1 1/4 = (4 * 1 + 1) / 4 = 5/4

Step 2: Convert the division operation to multiplication by taking the reciprocal of the second fraction: 12 ÷ (27/8) = 12 * (8/27)

Step 3: Perform the divisions: 12 * (8/27) = 96/27

Step 4: Convert the second mixed number to an improper fraction: 15/32

Step 5: Perform the division operation: (5/4) ÷ (15/32) = (5/4) * (32/15)

Step 6: Multiply the fractions: (5/4) * (32/15) = 160/60

Step 7: Simplify the fractions: 96/27 = 32/9 160/60 = 8/3

Finally, subtract the two results: 32/9 - 8/3

To subtract fractions, we need a common denominator. The least common multiple (LCM) of 9 and 3 is 9. So, we can rewrite the fractions with a common denominator:

(32/9) - (8/3) = (32/9) - (8/3) * (3/3) = (32/9) - (24/9) = (32 - 24)/9 = 8/9

Therefore, the expression 12 : (3 3/8) - (1 1/4) : (15/32) simplifies to 8/9.
