You can do this a number of ways.
The first way is to set up a proportion. That's very formal, and is most respected.
Proportion.
x / 60 = 1 / 10 The proportion is reduced by a factor of 10. Cross Multiply.
10 * x = 60 * 1
10x = 60 Divide by 10
x = 60/10
x = 6
Multiply by the scale factor.
Beginning number * scale factor = Final result.
60 * 1/10 = Final Result
60 * 1 / 10 = Final Result
Final Result = 6
This method words even when the numbers are quite complicated.
Step-by-step explanation:
For 8z = 40, z= 5. z is 5 and only 5
For 8z >= 40, z >=5, z can be a lot of numbers ranging from 5 upwards. The boundary for 8z >= 40 is 5 and 5 up
