Answer:
Explanation:
This number is in between 12.6 and 12.7 as shown on the number line.
This means that the number must be 12.60, 12.61, 12.62, 12.63, 12.64, 12.65, 12.67, 12.68, 12.69, or 12.70 (note that 12.6 and 12.60 are the same thing)
Now to find the exact decimal we see that the red dot is 4 jumps to the right of 12.6, meaning that it is 12.64. This is because the first line to the right is 12.61, the second line is 12.62, the third line is 12.63, the fourth line is 12.64.
To round to the nearest tenth, we need to look at the hundredths place. If the hundredths place is from 0-4, you round down, in this case to 12.6. If the hundredths place is from 5-9, you round up, in this case to 12.7.
Hope this helps!
