Answer 2

Let's solve the expressions step by step:

а) (16/33 × 5/7) × 11/16

Step 1: Multiply the fractions inside the parentheses: (16/33) × (5/7) = (16 * 5) / (33 * 7) = 80 / 231

Step 2: Multiply the result with the remaining fraction: (80/231) × (11/16) = (80 * 11) / (231 * 16) ≈ 0.1983 (rounded to 4 decimal places)

Therefore, the value of the expression (16/33 × 5/7) × 11/16 is approximately 0.1983.

б) 1 целая 3/5 × 3/4 + 1 целая 3/5 × 1/2

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

Step 2: Perform the multiplications: (8/5) × (3/4) = (8 * 3) / (5 * 4) = 24/20 = 6/5 (8/5) × (1/2) = (8 * 1) / (5 * 2) = 8/10 = 4/5

Step 3: Add the results: 6/5 + 4/5 = (6 + 4) / 5 = 10/5 = 2

Therefore, the value of the expression 1 целая 3/5 × 3/4 + 1 целая 3/5 × 1/2 is 2.
