To answer this question you need to know the conversion rate from kilometer into cm. For every kilometer it would be 1000m and for 1m it will be 100cm. That mean 1km is equal to 100,000cm or 10^5 cm. Then the answer would be:
(3.34 * 10^5 cm) * (1km/10^5cm)= 3.34km
Firstly we need to realize that 17/25 is as much as 68/100 (because 4 * 17 = 68 and 4 * 25 = 100). Now we can write it as a decimal of 0.68.
0.68 is a terminate decimal because there is no other digit than 0 we can add on its right hand side.
The answer is c.
I will explain
p - 2r = q
1. Move variable to the right by adding it’s opposites on both sides
p - 2r + 2r = q + 2r
2. Eliminate the opposites (-2r and +2r)
p = q + 2r
It would be 2 19/24 in simplest form as a mixed number.
