Some Answers
Use the model to answer these questions:
1. What is 75% of 120?
To find 75% of 120 with the model, drag the black dot so that 100% is 120. You should see that 75% is 90.
2. What is the whole if 45 is 75%?
To find the whole when 45 is 75%, drag the orange dot to 45 and read the whole at 100%. The whole should be 60.
3. If 75% of a number is 90, what is 25% of that same number?
To figure this one out with the model, drag the orange dot to 90 and look at where 25% is. It should be at 30.
4. If 75% of a number is more than 80, what could the number be?
To answer this one, try moving the orange dot to any number that is bigger than 80. Any number bigger than about 107 would be correct as the whole.
