Answer: 40/28 or 10/7 or 1 3/7

Explanation:

14/5 x 8/2

= 8 x 5 and 14 x 2

= 40 and 28

Thus, you would just put the 2 numbers in a fraction form to get your product.

If you want the simplified versions, you would get 10/7 or 1 3/7.

Answer:

Explanation:

To multiply 14/5 and 8/2 using cross multiplication, you can follow these steps:

Write the two fractions next to each other, separated by a multiplication sign:

14/5 x 8/2

Multiply the numerator of the first fraction by the denominator of the second fraction, and write the result as the numerator of a new fraction:

14 x 2 = 28

Write this as a fraction with the denominator of the first fraction:

28/5

Multiply the numerator of the second fraction by the denominator of the first fraction, and write the result as the numerator of a new fraction:

8 x 5 = 40

Write this as a fraction with the denominator of the second fraction:

40/2 = 20

Write the two fractions together as a product:

14/5 x 8/2 = 28/5 x 20

Simplify the product if possible. In this case, we can simplify by dividing both the numerator and denominator of 28/5 by 2:

28/5 = 14/5 x 2/2 = 14/5

So the final result is:

14/5 x 8/2 = 14/5 x 20 = 56
