Determine if 2.5/10= 12/48 or 2.5/2=12/24 is a proportion
To determine if 2.5/10 = 12/48 or 2.5/2 = 12/24 is a proportion, we need to check if the cross-products are equal.
For 2.5/10 = 12/48:
Cross-multiply: (2.5)(48) = (10)(12)
120 = 120
Since the cross-products are equal, 2.5/10 = 12/48 is a proportion.
For 2.5/2 = 12/24:
Cross-multiply: (2.5)(24) = (2)(12)
60 ≠ 24
Since the cross-products are not equal, 2.5/2 = 12/24 is not a proportion.
