Question

The Witches coven are making a potion and Ethel, Glinda, Locasta and Circe each add a different ingredient. When the potion is finished, there is 1/4 of the bat blood left, 1/3 of the knotgrass, 1/2 of the moonstone and 5/8 of the unicorn hair. Ethel used the most. Glinda used the least. Locasta used more than Circe. Who used the moonstone?

Answer 1

Math:

1/4 bat blood (Gina) = 6/24

1/3 knotgrass (Circe) = 8/24

1/2 moonstone (Locasta) = 12/24

5/8 unicorn hair (Ethel) = 15/24

First you need to find a common denominator for all the equations. Then you can solve your word problem.

(Primeiro tem que procurar um denominador comum para as frações, depois você consegue resolver o problema).
