15% off...
Total is always 100%. Hence with 15% off, you are left with (100-15) = 85%.
85% of 75
= (85/100) x 75
= 0.85 x 75
= 63.75

15% of 75. Rule is, move the decimal point 2 places to the left. It now becomes .15x75. So multiply 75 x .15
75
.15_
375
750 _
1125 -- move the decimal point 2 places to the left. Now it becomes 11.25
Sorry, I haven't yet learned how to underline on this stupid computer. Actually, I'm just ignorant as yet.
Of, always means times. 15% of 75 means .15x75
100% equals 1. So you move the decimal point 2 places to the left - 100% becomes 1.00 50% becomes .50, which is half of 1. 25% is .25. And if you multiply .25 x 100 you get 25.
If a dress is on sale that costs $100 and it's 25 % off, you do .25(move the decimal point 2 places to the left) x 100. .25 x 100
100
.25 ___
500
2000__
2500 move the decimal point 2 places to the left
25.00 So now you know the dress is $25.00 off. So instead of paying $100 you will pay 75. Hopefully I didn't confuse you because I haven't figured out how to underline. Maybe that's something you can teach me?

15 percent off of 75 = 75 - 75*15/100 = 75(1-15/100) = 75(1-0.15) = 75*0.85 = 63.75

this is soooooooo simple!
15 percent is 15/100 which is 0.15
all you have to do is is say 1-0.15 which is .85
and then .85 * 75 = 63.75
