5 calculators can be filled with a pack of 17 batteries

Explanation:

Given : A teacher brought a pack of 17 batteries

Each calculator uses 3 batteries.

To Find: How many calculator can the teacher fill with batteries?

Solution :

Since 3 batteries are used in 1 calculator

So, 1 battery is used in calculator =
`(1)/(3)`

So, 17 batteries are used in calculator =
`(17)/(3)`

=
`5(2)/(3)`

So, 5 calculators can be filled fully with 15 batteries

2 batteries will be remaining

Hence 5 calculators can be filled with a pack of 17 batteries
