To determine if 2.5/10 = 12/48 or 2.5/2 = 12/24 is a proportion, we need to cross multiply and see if the two ratios are equal.
For the first equation, 2.5/10 = 12/48:
Cross multiplying gives:
2.5 * 48 = 10 * 12
120 = 120
Since the cross multiplication is equal, 2.5/10 = 12/48 is a proportion.
For the second equation, 2.5/2 = 12/24:
Cross multiplying gives:
2.5 * 24 = 2 * 12
60 = 24
Since the cross multiplication is not equal, 2.5/2 = 12/24 is not a proportion.
Determine if 2.5/10 = 12/48 or 2.5/2 = 12/24 is a proportion
