Question

x.5 decimal number lines fwy
d the value of f. write your answer as a decimal number.
2.9 f 3.0
f =

Explanation:

Step1: Determine the interval length

The distance between 2.9 and 3.0 is $3.0 - 2.9 = 0.1$. There are 10 intervals (since from the first mark at 2.9 to the last at 3.0, count the number of spaces: from 2.9 to f is 1 space, and total to 3.0 is 10 spaces). So each interval length is $\frac{0.1}{10}=0.01$.

Step2: Find the value of f

Starting from 2.9, moving 1 interval (since f is the next mark after 2.9), so $f = 2.9+0.01 = 2.91$.

Answer:

2.91
