Question

fill in the missing numbers. find the positions of point a and point b.

Explanation:

Step1: Count total intervals

The number line from 0 to 1 is divided into 10 equal - sized intervals. Each interval has a length of $\frac{1}{10}=0.1$.

Step2: Locate point a

Point a is 3 intervals away from 0. So, $a = 3\times0.1=0.3$.

Step3: Locate point b

Point b is 5 intervals away from 0. So, $b = 5\times0.1 = 0.5$.

Answer:

$a = 0.3$
$b = 0.5$
