Given the number:
800
Decreased by 45%
Solution:
We must first determine 45% of 800. To do so, we need to convert 45% to decimal. In converting a percentage into decimal, divide the percentage by 100, hence in converting a decimal to percentage, multiply the percentage by 100.
= 45/100
= 0.45
Multiply 0.45 by 800, then subtract the product to 800
= (0.45)(800)
= 360
= 800 - 360
= 440
Final answer:
= 440
