EASY MATH PROBLEM!!!!!!!The number 75 is decreased by 40%, then the result is again decreased by 40%.What is the final result?
Question
Answer:
β΅ You need to simplify 40% by dividing 40 by 100 :40 Γ· 100 = 0,4
βΆ You need to calculate what 40% of 75 is by multiplying 40% (so 0,4) by 75 :
75 Γ 0,4 = 30
β· So the first time the number 75 decreased by 30. In order to know what number we are left with for the second part, we need to subtract 30 from 75 :
75 - 30 = 45
βΈ Now, you do the exact same thing as at the number ββΆβ, but instead you calculate what 40% of 45 is :
45 Γ 0,4 = 18
βΉ So the second time the number 45 decreased by β In order to know what the final result is, you need to subtract 18 from 45 :
45 - 18 = 27
β So the final result is : 27
I hope this helped! β»
