How would I calculate $139.00 by 40% the short way?

Question

Items cost $ 139.00 but need to get 40% off and need a short way to calculate on calculator.

Answer 1

Easy. Do a mental calculation. No need for any calculator.

Take the nearest large number, which is 140. You have to pay 60% of that price, right? (40% off).

140 * 6 = 84. (Take off a decimal).

Here is one: An item is 25% off. It sells for $101.99 How much will you pay?

Take 100 * 75 = $75 (take off decimals of course).

All this is approximate but you are quite close to the price you will be paying at the cash register. And, such quick calculation is good enough for shopping.

Answer 2

In any problem like this you need to multiply by the difference between this number and 100%. If you want to know what 40% off is, the other way of phrasing this is "what is 60% of the current value?" (100-40= 60)

Answer 3

Round $139.00 to $140.00. 10% would be $14.00 by just moving the decimal place to the left two places. (ones and then tens)
Then multiply 14 by 4 because that is 14+14+14+14 or 40%.
The answer us $56.00.
You can also multiply 14 by 4 by saying 10 times 4=40 plus 4 times 4 which is 16 and the answer would again be $56.00.

Answer 4

simply multiply the $139.00 by .60 (or 60%)

Think about it, if you are taking 40% off of an item, then the item will sell for 60% of it's original value.

Answer 5

If I understand your question, you are trying to get what the price would be after taking 40% off of 139? If this is the case take 139 x 60% and you would get 83.40

Answer 6

To get the amount to be paid, multiply $139 times .60 To get the discount, multiply 139 by .40

Answer 7

initially we could desire to discover the placement of the element V. As in line with the information abscissa of the element V is 40 six and of the preliminary end section of the line is 40 two ie. 40 six > 40 two. this suggests that the element is in the ambit of the projection of the line. Now, we could desire to understand in spite of if the element is above the line or under. to understand this we require slope of the line. to discover that evaluate the typical equation y = mx + c Then the slope of this line is, m = dy / dx = {{y(2)-y(a million)} / x(2) - x(a million)} Whence, x(a million), x(2), y(a million), y(2) are co-ordinates of the at as quickly as line AB. subsequently, the slope, m = (40-40 5)/(fifty two-40 two) = - 0.5 Then c = 40 5 -(-0.5 * 40 two) = sixty six hence, equation of the at as quickly as line is y = -0.5 *x + sixty six Now it incredibly is easy to discover the shortest distance to the at as quickly as line from the element V. For that purely enter the abscissa of the element in the equation of the at as quickly as line and get the corresponding ordinate of the at as quickly as line, ultimately discover the version from the ordinate of the element ; you get the shortest distance. ie. y= (-0.5*40 six) + sixty six = 40 3 Shortest distance is = 40 seven - 40 3 = 4 --------------------------------------...

Answer 8

You either can multiply the original value by the remaining price

139 * .60

or you can multiply it by .40 and get the discount, and subtract that from the original price

139- (139*.40)

Answer 9

0.4 * 139.00 will give you the discount on the item and
0.6 * 139.00 will give you the amount to be paid

Answer 10

139 x's .4
