Determine if 2.5/10=12/48 or 2.5/2 =12/24 is a proportion
To determine if either of these equations is a proportion, we need to see if the cross products are equal.
For the first equation:
2.5/10 = 12/48
Cross multiplying, we get:
2.5 * 48 = 10 * 12
120 = 120
Since the cross products are equal in this equation, it is a proportion.
For the second equation:
2.5/2 = 12/24
Cross multiplying, we get:
2.5 * 24 = 2 * 12
60 does not equal 24
Since the cross products are not equal in this equation, it is not a proportion.
Therefore, 2.5/10 = 12/48 is a proportion, while 2.5/2 = 12/24 is not a proportion.
