Carla wants to know how many batches of birdseed she can make with 1/2 cup of sunflower seeds. She puts 1/6 cup of sunflower seeds in every batch. Carla divides 1/2 by 1/6 to find the answer. She says this is the same as multiplying 1/6 by 2; explain what Carla did wrong and show the correct solution.

Answer:

she was wrong because when you divide 1/2 by 1/6 its not the same as multiplying 1/6 by 2 but you do get the same answer its just the wrong equation

Answer:

  • Carla inverted the numerator when she should have inverted the denominator before multiplying
  • 3

Explanation:

Any division problem is the same as a multiplication problem with the multiplier being the reciprocal of the denominator. So to divide 1/2 by 1/6, we could multiply 1/2 by (1/(1/6)) = 6/1. The result would be ...


(1)/(2)/(1)/(6)=(1)/(2)*(6)/(1)=(6)/(2)=\boxed{3}

Carla's mistake was inverting 1/2 instead of 1/6 in her solution to the problem.
