Represent on the number line.

**Solution:**

**(i)** Mark a line segment OB = 9.3 units on the number line where O represents 0 on the number line and point B represents -9.3.

**(ii)** Take OG = 1 unit.

**(iii)** Find midpoint A of BG and draw a semicircle taking A as its centre and AG as radius.

**(iv)** Draw a perpendicular EO to BG. Length of perpendicular EO

**(v)** Taking O as centre and OE as radius draw an arc intersecting number line at F. OF is units i.e point F represents on the number line.
