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

β“Ά 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

β“Έ Now, you do the exact same thing as at the number β€œβ“Άβ€, but instead you calculate what 40% of 45 is :

45 Γ— 0,4 = 18

β“Ή 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
