Unkown Percent

[rebecca12345]

I really need help with this i do not understand how to do this

Solve : What % of 16 is 4?

Step 1: These are the known numbers
% x 16=4

Step 2 Divide both sides of the equation by 16 to get the unkown number on one side of the equation by itself % X 16/16 = 4/16
%= 0.25

( this is what i need help with how are they dividing this what are they dividing it by how are they getting 0.25 percent out of this answer i have tried it and have only got 1/2??? I don't get this)

step 3: to get the solution into a percentage multiply times 100 and add the percent symbol 0.25 x 100 = 25 %

They are dividing both sides by 16

% X = 4/16

The right-hand-side gives you 1/4 which is equal to 0.25

% X = 1/4

% X = 0.25

out of this answer i have tried it and have only got 1/2??? I don't get this)

step 3: to get the solution into a percentage multiply times 100 and add the percent symbol 0.25 x 100 = 25 %

What % of 16 is 4?

I re-write these problems in the following way:

Replace

What ? x (unknown)

of ? * (multiplication)

is ? =

Now we have:

What % of 16 is 4? ? x % * 16 = 4

Now further replace

% ? /100 (divided by 100)

so we have

x / 100 * 16 = 4

x /100 * 16 /16 = 4/16 ( divide both sides by 16)

x/100 = 1/4

x/100 * 100 = 1/4 * 100 (multiply both sides by 100)

x = 25

done....
