find each product -7/9 x 3/5
a. -24/45
b. -7/15
c. 7/15
d. 27/45
geez! give somebody a chance to see your post and answer, before you start whining about it, ok?
My first inclination when I see such a short time delay between posts is just to ignore it. But, ...
when multiplying fractions, just multiply the tops and the bottoms:
-7/9 x 3/5 = -21/45
or, reduced, that is -7/15
- 7 / 9 x 3 / 5 = - 7 x 3 / 9 x 5 = - 21 / 45 = - 3 x 7 / 3 x 15 = - 7 / 15
To find the product of two fractions, you multiply their numerators together and their denominators together. Let's calculate the product of -7/9 and 3/5:
Product = (-7/9) * (3/5)
To multiply the numerators, we do -7 * 3, which gives us -21.
To multiply the denominators, we do 9 * 5, which gives us 45.
So the product of -7/9 and 3/5 is -21/45, which can also be written as -7/15.
Therefore, the correct answer is b. -7/15.
