A cotton candy vendor has 22 cones of blue cotton candy to sell. If the blue cotton candy is 50% of the total number of cones, h ow many total cotton candy cones does he have?
2 answers:
50% is another way of writing 0.50 or 1/2. Blue cotton candy is 50%, there are 22 blues, therefore 22 is 50% of the total number. Using algebra, 0.50x=22 X=44 Another way to think about this is simply to consider that 50% is half, and if 22 is half then one need only multiply by two to get the whole.
44. You can come to this answer by using algebra, 1/2x = 22 Multiply both sides by 2(denominator) thus, X = 44. Or you can use lateral thinking and realise that if 22 is 50%, you need to multiply by 2 to reach 100%.
