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.
