Step-by-step explanation:

Emily buys 3 pencils for 51p

Work out the price of 4 pencils.

51 : 3 * 4 = 68p

Answer:

68

Step-by-step explanation:

We can write a ratio to solve

3 pencils      4 pencils

------------- = -------------

51 p                x

Using cross products

3x = 51*4

3x = 204

Divide by 3

3x/3 = 204/3

x = 68
