Hey Netboy12121,

Move the decimal point one place to the left, to compute 10%. Then subtract that amount from the original price. For example, if it costs $29.95. 10% off, would be $2.99 - then you subtract $2.99 from $29.95. which is $26.96. Of course this does not account for taxes.

This works because we use base 10 as our system of math.

How To Calculate 10 Percent

2016-10-04 01:45:06 · answer #2 · answered by ? 4 · 0 0

If you're using a calculator, you would take the price and multiply it by 0.10.
For example, if a graphing calculator costs $96. Then, you would take 96 and multiply it by 0.1 or 0.10 (they mean the same thing) and it equals $9.60. If you want to know the total price of the product after that, then you would do this: $96-$9.60=$86.40.

An easy way to do this in your head, is to just move the decimal over. 10% of 5= 0.5. 10% of 47=4.7. 10% of 1000=100.

Let's say the item cost $35. Break it down into 10s and 5s. 10% of $10 is $1. So $1 x 3 = $3. Then we have the 5 dollars. Since 5 is hald of 10, split the $1, which would be 50 cents. so $3 + 50 cents is $3.50, your total price for the product is $31.50.

You could also just move the decimal place one place to the left, but the other way is just the longer way. (If you ever needed to explain it to somebody)
Hope this helps.

If you multiply the product price by .90, you will have the actual price minus the 10%. Notice, there's a decimal before the 9. No extra math needed. Well, except figuring tax....

if you want to know the discount you move the decimal place one to the left.

if you want to know the new price you can either take the original price and subtract it from the number created above, or just multiply the price by (.90) - the ninety is the percentage you'll pay for the item.

Since it's 10% off you're only paying 90%

If it is a 33% sale you pay: Asking Price * (100%-33%)
or Price * 67% which is Price * 0.67

if a shirt is 20$ then do 100-10=90 then 20 x 90 divided by 100

You can multiply the product by .1 to obtain the 10% figure, or you can multiply by .9 to obtain the figure (90%) you'll have when take 10% off the product.

Move the decimal point over one place. For example $10.00, move the decimal over and you get $1.00. So $1 is 10% of $10. (Then if you need other increments, say 20%, just start with 10 and then multiply.)

Take the price of the product, input it into the calculator (i.e. $10.97 = 10.97) and multiply it by .9 to find out the new price after the 10% is taken off.
