Final answer:
To calculate the amount of sugar in 2 1/2 packets, multiply the sugar content of one packet (9/10 ounces) by 2.5. The result is 2 1/4 ounces of sugar in 2 1/2 packets.
Step-by-step explanation:
The question asks how much sugar would be in 2 1/2 packets if one packet contains 9/10 ounces of sugar. To find the total amount of sugar in 2 1/2 packets, we multiply the amount of sugar in one packet by the number of packets:
1 packet = 9/10 ounces of sugar
2 1/2 packets = 2.5 packets
Total sugar = 9/10 ounces * 2.5
Total sugar = 9/4 ounces or 2 1/4 ounces
Hence, 2 1/2 packets of sugar contain 2 1/4 ounces of sugar.
