Visual Trick
Count spaces, not lines
Find the total difference and divide it by the number of equal spaces.
-
Step 1
Find the labelled difference: 600 − 400 = 200 mL.
-
Step 2
Divide 200 mL by four equal spaces to get 50 mL per space.
-
Step 3
Count 400, 450, 500, 550 to the water line.

Worked explanation
Why the answer makes sense
- The difference between 600 mL and 400 mL is 200 mL.
- Four equal spaces each represent 200 ÷ 4 = 50 mL.
- The third space above 400 mL is 400 + 3 × 50 = 550 mL.
