 Question from Errin: the price of the watermelon is directly proportional to its weight. If a watermelon that weighs 22 pounds cost $\$5.40,$how much will a 17.5 pound watermelon cost? Hi Errin, How much would a 11 pound watermelon cost?$\large \frac{22}{2} \normalsize = 11$so 11 is half of 22 and hence the 11 pound watermelon will cost$\large \frac{\$5.40}{2} \normalsize = \$2.70.$Likewise if a watermelon is one quarter the weight of the 22 pound watermelon it will cost one quarter of$\$5.40.$

What fraction of 22 pounds is 17.5 pounds?

I hope this helps,
Penny
