Answer:
YZ is 1 2/3
Explanation:
The whole thing is 3 units. One part is 1 1/3. Subtract to find the other part. We can change both numbers to improper fractions. Subtract by subtracting the top number (numerator) and just keep the bottom the same.
3 - 1 1/3 =
9/3 - 4/3=
5/3=
1 2/3
Or if you are practicing mental math (no pencil and paper) you can take away the 1 from the 3. Now you have 2 and you still need to subtract 1/3. If you take away 1/3 from 2, there will be 2/3 leftover and another 1 whole untouched. So you get 1 2/3 again!
