## Activity 1: Working with ratio

A company has a total of 150 employees and 25 of them are managers.
What is the ratio of managers to non-managers?

1. 1 to 3
2. 1 to 4
3. 1 to 5
4. 1 to 6
5. 2 to 5 

Solution
The company has 25 managers✓, so the remaining 125 employees are non-managers.✓
Express this ratio as a fraction and then reduce it:
Managers    = 25 = 1 ✓
Non-managers   125   5
✓The ratio of managers to non-managers is 1 to 5, so the correct answer is Choice (C) ✓✓. 

## Activity 2: Convert units of time

1.  A train journey takes 34 hours. How many days and hours does the journey take? (3)
2.  A plane trip (with stopovers) from South Africa to China takes 38 hours. How many days and hours does the trip take? (1) 
 Solutions 24 hours = 1 dayTherefore 34 hours = 34  = 1,417. ✓                                  24From our answer of 1,417 we know that we have 1 whole day and some remainder in hours. ✓We now work backwards to calculate the remainder:1 day = 24 hours34 hours – 24 hours = 10 hoursSo 34 hours = 1 day and 10 hours. (0,417 ´ 24 hours = 10 hours) ✓ 38 – 24 = 14The trip takes 1 day and 14 hrs. ✓
