Plot the number on the number line below:
The number line forms a type of track, on which there are lines (marks), each representing a number in ascending order,
The numbers go from left to right, meaning on the left side there is always a smaller number, and on the right a larger one.
The spaces between the marks are always fixed, thus if we count the "steps" between the numbers we know,
for example between 0.2 and 1, we can observe that it's four steps, meaning between each line there is a jump of 0.2.
The question we are being asked is where on the line is 1.4, therefore, we can start from the line that represents the number 1,
and move from it enough steps until we reach 1.4. In this case, it's two steps.
Determine the numerical value of the shaded area:
Look at two labeled numbers and count the spaces between them. From 1 to 1.8, there are 4 intervals, so each interval = .
In this problem, 1.4 does land exactly on a mark! Start at 1.0 and move two intervals to the right: 1.0 + 0.2 + 0.2 = 1.4.
Guessing often leads to errors! Always calculate the interval size first, then count systematically from a known point. This ensures accuracy.
The same method works! Find any two consecutive labeled points, calculate the interval size, then count from the nearest labeled point to your target number.
Count back to verify: From your 1.4 position, move 2 intervals left to reach 1.0, and 2 intervals right to reach 1.8. If this works, you're correct! ✓
