Which point marked on the following
number line represents 0.35?
In this question, we’re given a
number line which has three points 𝐴, 𝐵, and 𝐶 already marked. We have to select the point which
represents 0.35. Is it point 𝐴, 𝐵, or 𝐶? Let’s try and work out what each
interval on the number line is worth. So we start at zero and go up to
0.25, 0.50, 0.75, and another twenty-five hundredths takes us to one whole or a
hundred hundredths.
So if the difference between each
of our numbers is twenty-five hundredths, what is each division worth? It must be five hundredths: zero,
0.5, 0.10, 0.15, 0.20, 0.25. So we know that point 𝐴 represents
0.15. We’re looking for the point which
shows 0.35. Now that we’ve eliminated point 𝐴,
we know it’s got to be 𝐵 or 𝐶. Let’s carry on counting from 0.25:
0.30, 0.35. Point 𝐵 represents 0.35 and point
𝐶 represents 0.40. Out of our three points marked on
the number line, the one which represents 0.35 is point 𝐵. We worked out what each division on
the number line was worth. And we counted forward in five
hundredths each time until we found the point which represented 0.35. Point 𝐵 shows 0.35.
