Question

Tanya needs to buy chocolate bars for all the children in year 7. Each of the 130 children get one chocolate bar. There are 8 chocolate bars in each packet. Work out the least number of packets of chocolate bars that Tanya needs to buy.

Answer 1

17 packets

Explanation:

So Tanya needs 130 chocolate bars.

But there is 8 in each packet.

So, Divide

130 ÷ 8 = 16.25

16 packets

Answer 2

17 packets

Explanation:

So Tanya needs 130 chocolate bars.

But there is 8 in each packet.

So,

130 ÷ 8 = 16.25

16 packets

As you can see, there is a quarter left of chocolates that she needs (0.25). So what she can do is buy 1 more packet then give the quarter of that packet to the children.

So 16 + 1 = 17 packets
