Find the products. Use cancellation when possible.
7 x 4

8 5
Do you mean?
7 x 4
8 x 5
7 times 4 is 28 and 8 times 5 is 40
To find the products and use cancellation when possible, we can simplify the fractions before we multiply.
First, let's simplify the fraction on the left side:
7/8 = (7 ÷ 1) / (8 ÷ 1) = 7/8
Now, let's simplify the fraction on the right side:
4/5 = (4 ÷ 1) / (5 ÷ 1) = 4/5
Since there are no common factors to cancel in either fraction, we can simply multiply the numerators together to get the numerator of the product, and multiply the denominators together to get the denominator of the product:
(7/8) x (4/5) = (7 x 4) / (8 x 5)
Now, let's multiply the numerators and the denominators:
7 x 4 = 28
8 x 5 = 40
Therefore, the product is 28/40. To simplify the fraction, we can cancel the common factors between the numerator and the denominator:
28/40 = (28 ÷ 4) / (40 ÷ 4) = 7/10
So, the final product is 7/10.
