<h3>What is subtraction?</h3>
It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.
The expression is given below.
⇒ (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵)
Simplify the equation, then the value of the expression will be
⇒ (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵)
⇒ (7 x 10⁻¹³) − (0.042 x 10⁻¹³)
⇒ 6.958 x 10⁻¹³
The value of the expression (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵) will be 6.958 x 10⁻¹³. Then the correct option is C.

Answer:
10%
Step-by-step explanation:
Given:
Total number of racers = 270
Number of racers completed the race = 243
Number of racers gave up = 20
Now,
The number of racers who did not complete the race
= Total number of racers - Number of racers completed the race
= 270 - 243
= 27
Therefore,
The percentage of racers who did not complete the race
= 
= 
= 10%
