There are 10 marks between 7 and 8, therefore each mark is equivalent to 0.1

For 8.3, count 3 marks after 8:
[tex]8.3 \longrightarrow B[/tex]

First convert the fraction into decimal. Then count 6 marks from 7:
[tex] 7\dfrac{3}{5} = 7.6 \longrightarrow C[/tex]

Hey there :)

The number line has 0.1 spacing in between
                                          C    A                               D    B
<-|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|-----|--
  7    7.1   7.2  7.3  7.4  7.5 7.6  7.7   7.8  7.9   8   8.1  8.2 8.3

5. 8.3 ____ Since, they are spaced with a difference of 0.1, 8.3 is after the 8 on the number line. 

Therefore, point B is at 8.3

6. [tex]7 \frac{3}{5} [/tex] ____
[tex] 7\frac{3}{5} [/tex] is 7.6

Therefore, point C is at [tex]7 \frac{3}{5} [/tex]
