Question

elsie feels bad for Kevin and gives him 1/5 of her brownies. what fraction of the batch do they have?

Answer 1

If Elsie has 5 1/2, Kevin has 1/4 and Julian has 1/3. Then after giving away 1/5 of her brownies, Elsie would have given away;

E = 5 1/2 * 1/5

E = 11/2 * 1/5

E = 11/10

E = 1 1/10

If Elsie gave away 1 and 1/10 of her brownies, she now has;

E = 5 1/2 - 1 1/10

E = 11/2 - 11/10

(Take the LCM to be 10)

E = (55 - 11)/10

E = 44/10

E = 4 4/10

E = 4 2/5
