C is your answer, you tell without solving
So first (3 1/2) equals to 3+1/2 which is 7/2, same for(2 1/3), 2+1/3=7/3. It's asking for speed in laps per minute, so like how many labs did she swim per minute, which is labs over time——(7/2)/(7/3)=(7/2)*(3/7)=3/2. So she swam 3/2 labs per minute.
Answer:
1.32 kg
Step-by-step explanation:
Given a fraction of the market goods, we can find the remaining fraction by subtracting the given fraction from 1.
The fraction of the goods the farmer sells that is pears will be ...
