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 calculate both fractions and see if they are equal.
For 2.5/10 = 12/48:
2.5/10 = 0.25
12/48 = 0.25
Since both fractions are equal to 0.25, 2.5/10 = 12/48 is a proportion.
For 2.5/2 = 12/24:
2.5/2 = 1.25
12/24 = 0.5
Since 1.25 is not equal to 0.5, 2.5/2 = 12/24 is not a proportion.
Determine if one, both, or neither of the following is a proportion. 16/8 = ^? 24/12 , 8/4 =^? 12/6
To determine whether each pair of fractions is a proportion, we need to calculate the value of each fraction and see if they are equal.
For the first pair, 16/8 = 24/12:
16/8 = 2
24/12 = 2
Since both fractions are equal to 2, 16/8 = 24/12 is a proportion.
For the second pair, 8/4 = 12/6:
8/4 = 2
12/6 = 2
Since both fractions are equal to 2, 8/4 = 12/6 is also a proportion.
Therefore, both pairs of fractions are proportions.
