Here’s the big secret: a percentage is just a decimal in disguise. To find a percentage of a whole number, you must turn that percentage into a decimal first. Why? Because math is a sneaky beast, and it likes decimals.
How do you do that? You move the decimal point two places to the left. Yes, that’s it. So, 40% becomes 0.40. 25% becomes 0.25. 5% becomes 0.05. Just pretend you’re shooing a fly twice to the left. Pfft, pfft. Done.
If you forget this, just remember: percentages are like socialites—they love to be reduced to simpler numbers before they go out.
Let’s Test It On Those Sneakers
Alright, back to the $200 sneakers. We want 40% of $200. First, grab that 40% and turn it into a decimal: 0.40. Nod at it. You’re friends now.
Now, here’s the actual magic spell: Multiply the decimal by the whole number. So you do 0.40 × $200. That equals $80. Boom! Your discount is $80.
You just saved eighty bucks! You could buy a pizza with that. Or twelve fancy coffees. Or, you know, put it toward retirement. No judgment here.
