First Estimate the answer. Then find the exact answer. Simplify your answer if possible.

9*2/7*8/5/7

I would estimate this as 9 x 8 + 9 x 1/2 or

72+5

Would an estimate for the product of 34 and 56 be greater or less then the exact answer

To calculate this expression, let's break it down step by step:

Step 1: First, multiply 9 by 2 to get the numerator:
9 * 2 = 18

Step 2: Next, multiply 7 by 8 to get the denominator:
7 * 8 = 56

Step 3: Then, divide the numerator by the denominator from the previous step:
18/56

Step 4: Now, divide 5 by 7:
5/7

Step 5: Finally, divide the result from Step 3 by the result from Step 4:
(18/56) / (5/7)

To simplify the expression, we can multiply the numerator and denominator of the first fraction by 7:
(18/56) * (7/7) / (5/7)

Simplifying further, we have:
126/392 / (5/7)

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction:
126/392 * 7/5

Next, simplify the fraction by canceling out common factors:
(2 * 3 * 3 * 7) / (2 * 2 * 2 * 7 * 5)

Now, we can cancel out like terms:
(3 * 3) / (2 * 2 * 5)

Finally, we multiply the numbers in the numerator and denominator:
9 / 20

Therefore, the exact answer is 9/20.
