Answer 1

restaurant owner.

I bought 8 cakes for 8 parties, I cut 2 cakes into 3 parts because it meant to be served for 3 people, and similarly I cut 3 more cakes into 7 parts, and other 3 cakes into 8 parts.

Then someone came and ate a piece from each cake. How many piece are there left ?

Answer 2

So I cut the cakes

cake 1 3 / 3
cake 2 3 / 3

cake 3 7 / 7
cake 4 7 / 7
cake 5 7 / 7

cake 6 8 / 8
cake 7 8 / 8
cake 8 8 / 8

Answer 3

So I cut the cakes then someone eats/takes 1 peace from each

cake 1 3 / 3 - 1/3 = 2/3 of the cake
cake 2 3 / 3 - 1/3 = 2/3 of the cake

cake 3 7 / 7 - 1/7 = 6/7 of the cake
cake 4 7 / 7 - 1/7 = 6/7 of the cake
cake 5 7 / 7 - 1/7 = 6/7 of the cake

cake 6 8 / 8 - 1/8 = 7/8 of the cake
cake 7 8 / 8 - 1/8 = 7/8 of the cake
cake 8 8 / 8 - 1/8 = 7/8 of the cake

Answer 4

So I have left
3 × (7 / 8) from the cakes I cut for 3 different 8-people parties
3 × (6 /7) from the cakes I cut for 3 different 7-people parties
2 × (6 /7) from the cakes I cut for 2 different 3-people parties

(By the way, my question should be how many cakes are there left after all)

Answer 5

So, so far I am going to get \(\Large\color{blue}{ 3\frac{7}{8} + 3\frac{6}{7}+2\frac{2}{3} }\)

Answer 6

Then solve the question.

\(\Large\color{blue}{ 3\frac{7}{8} + 3\frac{6}{7}+2\frac{2}{3} }\)

Can you add it?
