Question

1 1/3 * (-3/4) - (-2 1/7) * 1 2/5

Answer 1

Вот решение, вроде нормально видно и вроде правильно

Answer 2

To calculate the expression, follow these steps:

Step 1: Convert mixed numbers to improper fractions. Step 2: Perform the multiplication and subtraction operations. Step 3: Convert the final answer back to a mixed number if necessary.

Let's begin:

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

Step 2: Perform the multiplication and subtraction operations 1 1/3 * (-3/4) - (-2 1/7) * 1 2/5 = (4/3) * (-3/4) - (-15/7) * (7/5)

Step 3: Simplify the fractions = -1 + 3 = 2

So, the result is 2.
