Some Answers
Use the model to answer these questions:
1. What is 25% of 120?
To find 25% of 120, drag the black dot so that 100% is 120. The orange dot should show you that 25% of 120 is 30.
2. What is the whole if 45 is 25%?
To find the whole if 45 is 25%, drag the orange dot so that 25% is 45. The black dot should show you that the whole is 180.
3. If 50% of a number is 80, what is 25% of that same number?
To use the model to answer this, drag either dot until you get the 50% mark to 80 on the number line. Then the orange dot will show you that 25% is 40. (And 100% is 160.)
4. If 25% of a number is more than 35, what could the number be?
To answer this, drag the orange dot to any place on the number line that is bigger than 35 and read the value of the whole. Any answer bigger than 140 is correct!
