Marion at Tattingstone School and Aditya, who is from Bristol Grammar, both calculated these percentages carefully and came to sensible conclusions!

- Have 10% of £5 or 75% of 80p. 10% of £5
is 50p:

10% of £5 = (10/100) * 500 = 5000/100 = 50

and 75% of 80p is 60p. I'd rather have the latter. - Have 60% of 2 pizzas or 26% of 5 pizzas. 60% of 2 is 1.2 and 26% of 5 is 1.3. Again, I'd rather have the latter.
- Get bitten by 15% of 120 mosquitoes or by 8% of 250 mosquitoes. 15% of 120 is 18 and 8% of 250 is 20. I'd prefer the first.
- Skip with a rope 54% of 105cm long or with one 88% of 2.75m long. 54% of 105cm is 56.7cm, and 88% of 2.75m is 2.42m = 242cm. I'd prefer using the longer rope.
- Get stuck in a traffic jam lasting 33% of 2 hours or 44% of 1 hr 40 mins. 33% of 120 minutes is 40 minutes, and 44% of 100 minutes is 44 minutes. I'd prefer neither!

Place this "worm" on the 100 square and find the total of the four squares it covers. Keeping its head in the same place, what other totals can you make?

There are six numbers written in five different scripts. Can you sort out which is which?

Put operations signs between the numbers 3 4 5 6 to make the highest possible number and lowest possible number.
