Answer:
55 = k
Explanation:
The scale factor is ⅖, which means if ⅖ of 15 is 6, then ⅖k is 22, so we set it up like this:
⅖k = 22 → 22[2½ (or 5⁄2)] >> 55
Dividing by a fraction is the same as multiplying by the fraction's multiplicative inverse.
Another way to solve this is to look at it proportionally:
[15][22]\6 = 55
