Are the ratios
25
45
and
15
27
proportional? Explain.
To determine if two ratios are proportional, we need to check if their cross products are equal.
The cross product is found by multiplying the numerator of one ratio with the denominator of the other ratio.
For the ratios 25 and 45, the cross product is calculated as 25 * 27 = 675.
For the ratios 15 and 27, the cross product is calculated as 15 * 45 = 675.
As the cross products of both ratios are equal, we can conclude that the ratios are proportional.
To determine if two ratios are proportional, we need to compare their cross products.
The cross products of the ratios 25:45 and 15:27 are calculated as follows:
For the first ratio (25:45):
Cross product = 25 x 27 = 675
For the second ratio (15:27):
Cross product = 45 x 15 = 675
Since both cross products are the same (675), the ratios are proportional.
