50% of a sum of money was £7.00. Find the whole sum of money.
Half of what is 7?
Or -- what is 2 times 7?
50% is the same as saying "half" of something, right?
So what is 7 half of?

To solve this problem, we can set up a proportion. Let's call the whole sum of money "x".
According to the problem, 50% of the whole sum is £7.00.
So we can write the proportion as:
(50/100) = 7/x
To solve for x, we can cross-multiply:
50x = 7 * 100
Now, let's solve for x:
50x = 700
Divide both sides by 50 to isolate x:
x = 700 / 50
x = £14.00
Therefore, the whole sum of money is £14.00.
