Question

There are 40 batteries in 10 pack. Gavin wants to know how many batteries are in 1 packs . Kylie wants to know how many batteries are in 5 packs drag an expression to answer each question

Answer 1

Divide the number of batteries by the amount of packs. 40/10=4. therefore each pack has 4 batteries. a bundle of 5 packs would be 20 batteries.
1x4= 4 same as 1 pack.
4x5= 20 same as 5 packs.
