A store manager is marking down chess boards from $25 to $14. What percentage is the discount?
Alborosie
Remember: when calculating percent it will always be over 100. With the given numbers 14 is your part out of the total (25). It should be written as part/whole.

As previously said, the percent is always over 100. (x/100)

In this problem you are given the part (14) and the whole (25). So it would be 14/25. The percent in this problem would be x/100. Now to find percent with the given part/whole, you would multiply 14 with 100. Then simply divide by 25.

tensa zangetsu [6.8K]

Correct Question:

A car/bus travels at a speed of 45 km/h. How far will it travel in 36 minutes?

(Note- Corrected part is written in bold.)

Solution:

\sf Speed = 45 \: km/h

\sf Time=36 \: mins

\sf   = \frac{36}{60} \:  hour \: (Since  \: we  \: know,1 \: hour \:  = 30 \: mins

\sf =  \frac{3}{5}  \: hour

\sf \: Distance = Speed \times Time

\sf =  \: 45 \times \frac{3}{5}  \: km

\sf   = \frac{45 \times 3}{5}  \: km

\sf \: Distance=27 \: km

  • Hence, a car/bus travels 27 km in 36 mins.
