Question

Someone please help me with this question, it’d be much appreciated!!

use cross products to determine whether the ratios 4/7 and 11/15 form a proportion. Do they form a proportion? Explain your steps and your conclusion

Answer 1

Using cross-multiplication, the ratios 4/7 and 11/15 do not form a proportion because cross-multiplying the numerator of one with the denominator of the other (60) does not equal the product of the other numerator and its corresponding denominator (77).

Step-by-step explanation:

To determine if the ratios 4/7 and 11/15 form a proportion, we can use the cross-multiplication method. This involves multiplying the numerator of one ratio by the denominator of the other ratio and comparing it to the product of the remaining numerator and denominator.

Let's calculate:

4/7 = 11/15

Cross-multiplying gives us:

4 x 15 = 7 x 11

Which simplifies to:

60 = 77

Since 60 does not equal 77, the two ratios do not form a proportion.

Answer 2

No, they do not form a proportion.

Step-by-step explanation:

Set up a proportion as 4/7 = 11/15

Cross multiply:

7×11

4×15

You should get 77 and 60 for the products. Since the products don't equal each other, they are not proportional.
