is 3/11=7/19 a proportional fraction
To determine if two fractions are proportional, we can check if their cross products are equal. In this case, the cross products are obtained by multiplying the numerator of the first fraction by the denominator of the second fraction, and vice versa.
Let's check whether the cross products are equal:
Cross product of the first fraction = (3 * 19) = 57
Cross product of the second fraction = (7 * 11) = 77
Since the cross products (57 and 77) are not equal, we can conclude that 3/11 is not proportional to 7/19.
