Answer 1

Answer:

5 calculators can be filled with a pack of 17 batteries

Step-by-step 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 = $\frac{1}{3}$

So, 17 batteries are used in calculator = $\frac{17}{3}$

                                                               =$5\frac{2}{3}$

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
