Question

7/8*(5/7-3/4) ПЛИИИЗ

Answer 1

$\frac{7}{8} * (\frac{5}{7} - \frac{3}{4}) = -\frac{1}{32}\\\\1) \frac{5}{7} - \frac{3}{4} = \frac{20}{28} - \frac{21}{28} =-\frac{1}{28}\\\\2) -\frac{1}{28} * \frac{7}{8} = -\frac{7}{28*8} = -\frac{1}{32}$

Answer 2

7/8*(5/7-3/4)=7/8*(-1/28)=-1/8*1/4=-1/32

Answer 3

Sure, I'd be happy to help you solve the expression!

To evaluate the expression 7/8 * (5/7 - 3/4), follow these steps:

Step 1: Simplify the expression inside the parentheses. 5/7 - 3/4

To subtract fractions, you need to find a common denominator. In this case, the common denominator is 28 (the least common multiple of 7 and 4).

Step 1a: Convert 5/7 to have a denominator of 28: (5/7) * (4/4) = 20/28

Step 1b: Convert 3/4 to have a denominator of 28: (3/4) * (7/7) = 21/28

Now, the expression inside the parentheses becomes: 20/28 - 21/28

Step 2: Subtract the fractions inside the parentheses: (20/28) - (21/28) = -1/28

Step 3: Now, multiply the result by 7/8: 7/8 * (-1/28)

Step 4: Finally, multiply the numerators and denominators: (7 * -1) / (8 * 28) = -7/224

The final answer to the expression 7/8 * (5/7 - 3/4) is -7/224.
