Let鈥檚 see what Jerry and Albert are buying for their holiday.
Looking good! We should work out how much money they鈥檒l need. Let鈥檚 make a rough estimate by rounding the costs to the nearest pound.
Alberts swimming trunks are 拢4.99, because the amount ends in more than 50p, we round up to 拢5.
His snorkel is 拢2.20 which means the amount ends in less than 50p, so we round down to 拢2.
Alberts goggles are 拢3.50. Because 拢3.50 is exactly half-way between 拢3 and 拢4, we round up.
In total, Jerry and Albert will need about 拢11 for their holiday shop.
Don鈥檛 forget though, if you鈥檙e rounding down money to the nearest pound, you may need a little bit extra when you get to the tills.
If you want a more accurate estimation, you can round to the nearest 50p. You can round 拢1.45 to 拢1.50.
Eh鈥 just make sure you always keep your receipt.
Rounding money or decimals
Rounding a price to the nearest pound is the same as rounding a decimal to the closest whole number.
If the price is 拢2.80 you can round up to 拢3 because the number in the tenths position is 8. The closest whole number to 2.8 is 3.
If the price is 拢2.08 you can round down to 拢2 because the number in the tenths position is 0. The closest whole number to 2.08 is 2.
Don't forget, if the number you are rounding is 5, round up. 拢2.50 rounded to the nearest pound is 拢3.
