Answer 2

To calculate the expression 2 2/9 ÷ 1 2/5 × 3 3/4, follow these steps:

Step 1: Convert mixed numbers to improper fractions. 2 2/9 = (2 * 9 + 2)/9 = 20/9 1 2/5 = (1 * 5 + 2)/5 = 7/5 3 3/4 = (3 * 4 + 3)/4 = 15/4

So, the expression becomes:

(20/9) ÷ (7/5) × (15/4)

Step 2: Divide and multiply the fractions. To divide fractions, multiply by the reciprocal of the second fraction.

(20/9) ÷ (7/5) × (15/4) = (20/9) × (5/7) × (15/4)

Now, multiply the numerators together and the denominators together:

(20 * 5 * 15) / (9 * 7 * 4)

Step 3: Simplify the fractions. Calculate the products in the numerator and denominator:

Numerator: 20 * 5 * 15 = 1500 Denominator: 9 * 7 * 4 = 252

So, the expression simplifies to:

1500/252

Step 4: Reduce the fraction to its simplest form. To simplify the fraction further, find the greatest common divisor (GCD) of 1500 and 252, and then divide both the numerator and denominator by the GCD.

GCD(1500, 252) = 12

Divide both the numerator and denominator by 12:

(1500/12) / (252/12) = 125/21

So, the simplified result of the expression 2 2/9 ÷ 1 2/5 × 3 3/4 is 125/21.
