Answer:

21

Step-by-step explanation:

given : 2 triffles = 7

6 / 2 = 3 so miutiple both side by 3

2 x 3 = 6 and 7 x 3 = 21

6 triffles = 21

OR

Find the cost of 1 triffle:

7 / 2 = 3.5

1 triffle = 3.50

3.50 each x 6 triffles = 21
2 trifles cost £7. So to find 1 you divide 7 by 2 which gives you £3.50.

So then now you know one costs £3.50 and you need to find the cost of 6 you do

3.50 x 6= 21

Answer: £21
