The table shows that Jesse can complete 48 math problems in 8 minutes. Since 8 minutes is 1/8 of 1 hour, we can find the rate of math problems per minute by dividing 48 by 8:
48 problems / 8 minutes = 6 problems per minute
Therefore, Jesse can complete 6 math problems in 1 minute.
To find the number of math problems she can complete in 15 minutes, we can multiply the rate of problems per minute by the number of minutes:
6 problems per minute * 15 minutes = 90 problems
So, Jesse can complete 90 math problems in 15 minutes.
The correct answer is: 6; 90
wrong
I apologize for the mistake. Let's go through the table again.
We know that Jesse can complete 48 math problems in 8 minutes. To find how many math problems she can complete in 1 minute, we can divide the number of problems by the number of minutes:
48 problems / 8 minutes = 6 problems per minute
Therefore, Jesse can complete 6 math problems in 1 minute.
To find how many math problems she can complete in 15 minutes, we can multiply the rate of problems per minute by the number of minutes:
6 problems per minute * 15 minutes = 90 problems
So, Jesse can complete 6 math problems in 1 minute and 90 math problems in 15 minutes.
The correct answer is: 6; 90
so it is 7, 22
I apologize for the confusion. Let's go through the table again.
We know that Jesse can complete 48 math problems in 8 minutes. To find how many math problems she can complete in 1 minute, we can divide the number of problems by the number of minutes:
48 problems / 8 minutes = 6 problems per minute
Therefore, Jesse can complete 6 math problems in 1 minute.
To find how many math problems she can complete in 15 minutes, we can multiply the rate of problems per minute by the number of minutes:
6 problems per minute * 15 minutes = 90 problems
So, Jesse can complete 6 math problems in 1 minute and 90 math problems in 15 minutes.
The correct answer is: 6; 90

The table shows that for every 4 blue crayons, there are 3 white crayons.
To find how many white crayons there are if there are 8 blue ones, we can use the ratio:
4 blue crayons / 3 white crayons = 8 blue crayons / x white crayons
Cross multiplying, we get:
4x = 8 * 3
Simplifying, we get:
4x = 24
Dividing both sides by 4, we find that x = 6.
So, if there are 8 blue crayons, there will be 6 white crayons.
Similarly, to find how many blue crayons there are if there are 12 white ones, we again use the ratio:
4 blue crayons / 3 white crayons = y blue crayons / 12 white crayons
Cross multiplying, we get:
3y = 4 * 12
Simplifying, we get:
3y = 48
Dividing both sides by 3, we find that y = 16.
So, if there are 12 white crayons, there will be 16 blue crayons.
The correct answer is: 6; 16
