Answer 2

It looks like you have a complex expression with fractions and multiplication. Let's break it down step by step:

Expression 1: (1 1/3 * 3.4 * 2 4/7) / (2 2/7 * 3.8 * 1 1/5)

Let's simplify the fractions and the multiplication: (4/3 * 3.4 * 18/7) / (16/7 * 3.8 * 6/5)

Now, calculate each part: (4/3 * 3.4 * 18/7) = (4 * 3.4 * 18) / (3 * 7) = 244.8 / 21 (16/7 * 3.8 * 6/5) = (16 * 3.8 * 6) / (7 * 5) = 364.8 / 35

Now, divide the two results: (244.8 / 21) / (364.8 / 35)

To divide fractions, multiply the first fraction by the reciprocal of the second fraction: (244.8 / 21) * (35 / 364.8)

Now, perform the multiplication: (244.8 * 35) / (21 * 364.8)

Calculate the numerator and denominator separately: Numerator: 244.8 * 35 = 8556 Denominator: 21 * 364.8 = 7660.8

Now, divide the numerator by the denominator: 8556 / 7660.8 ≈ 1.117

So, the result of the first expression is approximately 1.117.

Expression 2: (1 2/7 * 1.7 * 5 1/3) / (1 9/ 2 2/5 * 1 1/6)

Let's simplify the fractions and the multiplication: (15/7 * 1.7 * 16/3) / (25/9 * 7/6)

Now, calculate each part: (15/7 * 1.7 * 16/3) = (15 * 1.7 * 16) / (7 * 3) = 408 / 7 (25/9 * 7/6) = (25 * 7) / (9 * 6) = 175 / 54

Now, divide the two results: (408 / 7) / (175 / 54)

To divide fractions, multiply the first fraction by the reciprocal of the second fraction: (408 / 7) * (54 / 175)

Now, perform the multiplication: (408 * 54) / (7 * 175)

Calculate the numerator and denominator separately: Numerator: 408 * 54 = 22032 Denominator: 7 * 175 = 1225

Now, divide the numerator by the denominator: 22032 / 1225 ≈ 18

So, the result of the second expression is approximately 18.

Therefore, the final result of the entire expression is approximately 1.117 / 18, which simplifies to approximately 0.062.
