Answer:
Let x be the original price of the shirt. We know that the sale price is 25% off the original price, which means that the sale price is 75% of the original price.
In other words, 0.75x = 45.
To find x, we can divide both sides by 0.75:
x = 45 ÷ 0.75
x = 60
Therefore, the original price of the shirt was £60.
