Harry lost 15p, which was 3/4 of his money. How much had he at first?
(3/4)x = 15
Solve for x.
20p
To find out how much Harry had at first, we can use the concept of ratios. Since he lost 15p, which was 3/4 of his money, we can set up the equation:
(3/4) * x = 15p
To solve for x, we'll divide both sides of the equation by 3/4:
x = (15p) / (3/4)
To simplify, we can multiply the numerator by the reciprocal of the denominator:
x = 15p * (4/3)
Multiplying 15p by 4/3, we get:
x = 20p
Therefore, Harry had 20p at first.
To find out how much money Harry had at first, we can set up an equation using the given information.
Let's assume that the amount of money Harry had at first is represented by "x" pence.
According to the problem, Harry lost 15p, which was 3/4 of his money. This means that:
3/4 * x = 15
To solve this equation, we can multiply both sides by 4/3 to cancel out the fraction:
(4/3) * (3/4 * x) = (4/3) * 15
This simplifies to:
x = 20
Therefore, Harry had 20 pence at first.
