Question

Determine if 2.2510=?940
, 2.510=?9040
, or 2.2512=?9040
is a proportion.

Answer 1

To determine if these expressions form a proportion, we need to check if the cross products are equal.

For the first pair: 2.25 * 940 = 2115
10 * x = 10x

Since the cross products are not equal, 2.25=?940 is not a proportion.

For the second pair: 2.5 * 9040 = 22600
10 * x = 10x

Again, the cross products are not equal, so 2.510=?9040 is not a proportion.

For the third pair: 2.25 * 9040 = 20340
12 * x = 12x

The cross products are also not equal, so 2.2512=?940 is also not a proportion.

Therefore, none of the given expressions form a proportion.
