Question

Each snack pack holds 20 crackers. How many crackers in all are there in 4 snack packs?

Answer 1

The answer is 80 crackers

Explanation:

From the question, it is said that each snack pack has 20 crackers. From this, we have to find how much crackers are in 4 snack packs.
It is probably best, to use the idea of relation when finding the answer to this problem.

`1:20=4:x` which can be read "if in one there are 20, then in 4 there are x

Now we are trying to find the amount of snacks in total (in the 4 packs). When solving a relation, you multiply the two numbers in the middle or the two in the extremes ( depending on which one there is not the unknown), and then you divide the product by the extreme/middle number left.

`x= (4*20)/1= 80` crackers
