Tim needs to apply 21/2 gallons of herbicide per acre of soybeans. How many gallons of herbicide are needed for 360 acres?

A worker has readings that take 22/3 minutes each to read and record. How many readings can be completed in 192 minutes?

A grocer sold 16 bags of potatoes for $1.08 each. What was the total amount of the sale?

2.5 * 360 = ?

Or is it 21/2 = 10.5?

Is it 22/3 = 7 1/3 or 2 2/3 = 2.67?

16 * 1.08 = ?

I got:

1.900

2. 72

3. $17.28

are these correct?

To get the answer to the first question, we multiply the number of gallons needed per acre by the number of acres.

In this case, Tim needs 21/2 gallons of herbicide per acre and he has 360 acres of soybeans.

So the calculation would be: (21/2) x 360 = 1890 gallons of herbicide needed for 360 acres of soybeans.

Therefore, Tim would need 1890 gallons of herbicide for 360 acres of soybeans.

To get the answer to the second question, we divide the total time available by the time taken for each reading.
In this case, a worker takes 22/3 minutes to read and record each reading and he has 192 minutes available.

So the calculation would be: 192 รท (22/3) = 192 x 3/22 = 6264/22 = 284 readings can be completed in 192 minutes.

Therefore, the worker can complete 284 readings in 192 minutes.

To get the answer to the third question, we multiply the number of bags sold by the price per bag.
In this case, the grocer sold 16 bags of potatoes and each bag was sold for $1.08.

So the calculation would be: 16 x $1.08 = $17.28

Therefore, the total amount of the sale for the grocer was $17.28.
