Answer:
17 packets
Step-by-step 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
