Question

Find the product.


4 over 7(−20 over 2)

-2 over 35

5 and 5 over 7

-5 and 5 over 7

-9 and 3 over 7

Answer 1

To find the product, we multiply the fractions.

First, we simplify the expression 4/7 * (-20/2).

4/7 * (-20/2) = (4 * -20) / (7 * 2) = -80/14 = -40/7

So the product of 4/7 * (-20/2) is -40/7.

Now, let's simplify the expression -2/35.

The product of -2/35 is already simplified.

Next, we simplify the expression 5 and 5/7.

5 and 5/7 can be written as a mixed number (5 + 5/7). We need to convert it to an improper fraction.

(5 * 7 + 5) / 7 = 40 / 7 = 5 and 5/7

So the product of 5 and 5/7 is 5 and 5/7.

Lastly, we simplify the expression -5 and 5/7.

To find the product, we multiply -5 and 5/7 by -9 and 3/7.

(-5 and 5/7) * (-9 and 3/7)

To calculate the product of mixed numbers, we first convert them into improper fractions.

-5 and 5/7 = (-5 * 7 + 5) / 7 = -40/7

-9 and 3/7 = (-9 * 7 + 3) / 7 = -60/7

Now we multiply the fractions:

(-40/7) * (-60/7) = (40 * 60) / (7 * 7) = 2400/49

Therefore, the product of -5 and 5/7 * -9 and 3/7 is 2400/49.
