Write 3 multiplication statements that have the same product as (-4/9)(7/5).
The product of the two given fractions is:
`-4/9 xx 7/5 = -28/45`
To compose multiplication statements that would result to the same product, we may consider the prime factorization of the numbers present in our product.
`28 = 2xx2xx7`
Hence, some of the multiplication statements that would have the same product as above are:
To solve (-4/9)(7/5) you can multiply straight across (multiply the numerators and then the denominators), and you get (-28/45).
To help you choose your numerators, you need to find 2 or more numbers that multiply to make 28. Examples would be 4 and 7, 2 and 14, and 1 and 28.
You need to do the same for the denominators. Numbers that multiply to make 45 include 5 and 9, and 3 and 15.
Since multiplying fractions is simply multiplying the numbers in the top over the numbers is the bottom, you can make fractions with a combination of these numbers listed above. However, make sure you make one fraction negative.
