Use cross multiplication to decide whether the following proportion is true or false.
7/4 = 35/16
To decide whether the proportion is true or false using cross multiplication, we can cross multiply the numerator of the first fraction with the denominator of the second fraction and vice versa.
For this proportion, cross multiplying gives us:
7 * 16 = 4 * 35
112 = 140
Since 112 is not equal to 140, the proportion is false.
