Question

Решите: (7 3/5 • 4 4/9) • (9/38 • 5/8) + 5 = ?

Answer 1

(7 3/5 • 4 4/9) • (9/38 • 5/8) + 5 = 10

Answer 2

To solve the given expression, follow these steps:

Step 1: Convert mixed numbers to improper fractions. Step 2: Perform the multiplications inside the parentheses. Step 3: Perform the multiplications outside the parentheses. Step 4: Perform the addition with 5.

Let's start:

Step 1: Convert mixed numbers to improper fractions. (7 3/5) = (75 + 3)/5 = 38/5 (4 4/9) = (49 + 4)/9 = 40/9

Step 2: Perform the multiplications inside the parentheses. (38/5 • 40/9) = (38 * 40) / (5 * 9) = 1520 / 45

Step 3: Perform the multiplications outside the parentheses. (9/38 • 5/8) = (9 * 5) / (38 * 8) = 45 / 304

Step 4: Perform the addition with 5. (1520 / 45) • (45 / 304) + 5 = (1520 * 45) / (45 * 304) + 5 = 1520 / 304 + 5 = 5 + 5 = 10

Therefore, the result is 10.
