Percentage Of A Figure

2017-01-01 12:32:07 · answer #2 · answered by vierra 4 · 0 0

Simply take the percentage i.e. 40% place it on the right of the decimal point and place a 1 on the left.

1.40

multiply the number you wish to add the 40% to for example
if I want to add 40% of 50 to itself :

1.40 x 50

equals 70

If you just want to find 40% then just place the 40 to the right of the decimal point and zero to the left i.e.

0.40

To find 40% of 50 for example :

0.40 x 50

equals 20


If you want to find your percentage amount and you know the percentage you multiplied by then :

percentage
--------------- x total = percentage amount
100

this is handy when trying to work out a net amount when you know the VAT rate. i.e.

17.5
------- x Gross amount = Vat Amount
100

or to simplify

7
--- x Gross Amount = Vat Amount
47

then simply take one away from the other to get the Net Amount

just multiply by 1.4
example: to add 40% to 100
multiply 100 by 1.4
This gives 140 which is 100+40% of 100

Got your calculator?
multiply the figure by (100+ desired %)/100
eg for 40%-- X x 140/100

Calculator : times by 1.4

or

Without : find 10% which is move decimal point once to left and times by 4 to get 40 % and add it on to the number

Take your starting figure and multiply it by .40

This will tell what 40% is. Then just add that to your original figure.

Simple.

Divide by 100 and multiply by 140...

Take those figures as 100%, then solve for 140%.

e.g. Let the figure you're working with be 80.

100% --> 80
140% --> (80/100)*140 = 112

Any number divided by 100 will give you 1% of that number. Just multiply 1% by the number of percent you want.
