Answer:
40 pencils for 6 pounds.
Explanation:
To find out how many pencils can be bought for 6 pounds, we can set up a proportion using the given information.
First, determine the cost of one pencil. We divide the total cost of 12 pencils (£1.80) by the number of pencils, which gives us £1.80/12 = £0.15 per pencil.
Now, we can set up a proportion:
£0.15 per pencil = £6 for x pencils.
To solve for x, we cross-multiply and divide:
£0.15 * x = £6
x = £6 / £0.15
x = 40
Therefore, you can buy 40 pencils for 6 pounds.
