Final answer:
To calculate the amount of sugar in 2 1/2 packets when one packet contains 9/10 ounces, multiply 9/10 by 2 1/2 to get 9/4, which is 2 1/4 ounces of sugar.
Step-by-step explanation:
To find out how much sugar would be in 2 1/2 packets, we first need to determine how much sugar is in one packet.
The question tells us that one packet contains 9/10 ounces of sugar.
To find the amount of sugar in 2 1/2 packets, we multiply the amount in one packet by 2 1/2.
2 1/2 multiplied by 9/10 can be calculated as:
2 1/2 * 9/10
= 5/2 * 9/10
= 45/20
= 9/4
Therefore, there would be 9/4 ounces of sugar in 2 1/2 packets.
