Mrs Larnell is making a snack packs for a a class picnic. She puts 1/4 pound of apples,1/8 pound of nut mix, and 1/16 pound of chocolate in each of the students packs. There are 24 students in the class.What is the total weight of the snack packs? Is there more than one way to solve this problem?

Answers

Answer=10 1/2 pounds

One pack has 1/4+1/8+1/16 pounds of snacks....

Lets starts off giving our fractions of 1/4, 1/8 and 1/16 a common denominator of 16.

1/4=4/16
1/8=2/16
1/16=1/16

So...

x=4/16+2/16+1/16
x=7/16

So... One pack has 7/16lbs of snacks in it

Multiply 7/16lbs by the total number of students(24)..

7/16*24=10 1/2 pounds
________________________________________________________
another way of solving this problem could be...

1/4*24=6
1/8*24=3
1/16*24=1.5

6+3+1.5=10.5 pounds

I will write your question as an equation:

and we need to find the x. For this, we multiply both sides by 10:

200 000 =x

so the answer is 200 000
