Question

Use cross-multiplication to check if the proportion is true: (2)/(9)=(0.14)/(0.67)

Answer 1

The proportion (2/9) = (0.14/0.67) is checked using cross-multiplication. After calculating, it's found that 2 x 0.67 is not equal to 0.14 x 9, hence the proportion is not true.

Step-by-step explanation:

To check if the proportion (2/9) = (0.14/0.67) is true by using cross-multiplication, we multiply the numerator of one ratio by the denominator of the other ratio and compare to see if both products are equal.

• First, multiply the numerator of the first ratio by the denominator of the second ratio: (2) x (0.67).
• Second, multiply the numerator of the second ratio by the denominator of the first ratio: (0.14) x (9).

Now, check if these two products are equal:

2 x 0.67 = 1.34

0.14 x 9 = 1.26

Since 1.34 is not equal to 1.26, the given proportions are not equal, and the proportion (2/9) = (0.14/0.67) is not true.
