5 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

Tanya needs to purchase a chocolate bar for every one of the 130 kids. Given that there are 8 chocolate bars in each packet, we need to establish the number of packets required. For this purpose, we'll employ division. Step 1: First, ascertain the total amount of chocolate bars required. Given that every one of the 130 kids gets a bar, Tanya would need 130 bars. This step is basic and wealready know how many bars are required. Step 2: Next, determine how many packets of 8 bars Tanya will need. Dia means she has to divide the total number of bars by the number of bars in one packet, as such \[\text{Number of packets} = \frac{required\ bars}{bars\ in\ one\ packet} = \frac{130}{8} = 16.25 \] However, Tanya can't purchase 0.25 of a packet, so we need to round up this number since .25 packet means she will be short of chocolate bars. In other words, she needs 1 more packet. Rounding 16.25 up yields 17. Therefore, the least number of packets of chocolate Tanya has to purchase is \[17 packets\].
