My homework is Use fraction strips to find the difference.. How do you do that? Exp..... 1/2/-1/3
1/2-1/3=3/6-2/6-1/6
Answer is 1/6
1/2-1/3=3/6-2/6-1/6
3/6 - 2/6 = 3/6 -2/6 - 1/6
1/6 = 1/6
Sorry, I goofed.
1/6 = 0
However, 3/6 - 2/6 = 1/6
It would help if you proofread your questions before you posted them. You seem to use dashes, when equal sign is applicable.

To use fraction strips to find the difference between two fractions, you can follow these steps:
1. Start by drawing two fraction strips: one for each fraction.
2. For the first fraction, divide the strip into equal parts according to the denominator. In this case, the first fraction is 1/2, so you would divide the strip into 2 equal parts.
3. Shade the appropriate number of parts to represent the numerator of the first fraction. Since the numerator is 1, shade 1 out of the 2 parts.
4. Repeat steps 2 and 3 for the second fraction. The second fraction is -1/3, so divide the strip into 3 equal parts and shade -1 out of the 3 parts.
Now, to find the difference between the two fractions, you need to subtract the shaded portions.
5. Combine the strips together, one above the other, aligning them at the left end.
6. Count the remaining shaded parts on the combined strips. In this case, you should have 3 shaded parts from the first strip (1/2) and 2 shaded parts from the second strip (-1/3).
7. Simplify the difference by finding a common denominator. In this example, the common denominator is 6.
8. Convert both fractions to have a denominator of 6 by multiplying the numerator and denominator by the appropriate factor. The first fraction becomes 3/6, and the second fraction becomes -2/6.
9. Finally, subtract: 3/6 - 2/6 = 1/6
Therefore, the difference between 1/2 and -1/3 is 1/6.
