Question

below are several lines with units of distance marked on them.
the scale for each line is labeled below the line.
for each line, you are asked to click in a box at a given length on the line. when you click in a box, the value you are asked for will appear.
if you decide that the box you clicked on is not the correct length, click in the box again and the value will disappear. then, click in the box that you think is correct.
click in the box with the blue arrow pointing to 1 yard on this line:
line with 0, 1 m, 2 m and boxes with blue arrows
click in the box with the blue arrow pointing to 1 meter on this line:
line with 0, 1 ft, 2 ft, 3 ft, 4 ft, 5 ft and boxes with blue arrows
click in the box with the blue arrow pointing to 250 centimeters on this line:
line with 0, 1 m, 2 m, 3 m and boxes with blue arrows

Explanation:

Step1: Convert yard to meter

We know $1 \text{ yard} = 0.9144 \text{ m}$.

Step2: Locate on first number line

The first line spans 0 to 2 m. 0.9144 m is just left of the 1 m mark, so this is the 3rd box (from left).

Step3: Convert meter to feet

We know $1 \text{ meter} \approx 3.2808 \text{ ft}$.

Step4: Locate on second number line

The second line spans 0 to 5 ft. 3.2808 ft is just right of the 3 ft mark, so this is the 4th box (from left).

Step5: Convert cm to meter

$250 \text{ cm} = \frac{250}{100} = 2.5 \text{ m}$.

Step6: Locate on third number line

The third line spans 0 to 3 m. 2.5 m is halfway between 2 m and 3 m, so this is the 5th box (from left).

Answer:

1. For 1 yard: Click the 3rd box (left to right, just left of 1 m mark)
2. For 1 meter: Click the 4th box (left to right, just right of 3 ft mark)
3. For 250 centimeters: Click the 5th box (left to right, halfway between 2 m and 3 m)
