Rounding to the Nearest 10 www.seomraranga.com Rounding to the Nearest 10 Decide: Which two tens is the number between Which ten is it nearest to

Rounding to the Nearest 10 www.seomraranga.com Rounding to the Nearest 10 Rules: If it ends in numbers 1 to 4 round to the ten before If it ends in numbers 6 to 9, round to the ten after If it ends in 5 (which is half way between two tens) always round up to the higher ten

Rounding to the Nearest 10 www.seomraranga.com Rounding to the Nearest 10 Example 1 Round off 134 It is between 130 and 140 It ends in 4, so it rounds down to 130 (You only have to go back 4 to get to 130, but you would have to go forward 6 to get to 140)

Rounding to the Nearest 10 www.seomraranga.com Rounding to the Nearest 10 Example 2 Round off 357 It is between 350 and 360 It ends in 7, so it rounds up to 360 (You only have to go forward 3 to get to 360, but you would have to go back 7 to get to 350)

Rounding to the Nearest 10 www.seomraranga.com Rounding to the Nearest 10 Example 3 Round off 575 It is between 570 and 580 It ends in 5, so it rounds up to 580 (The rule is that when it ends in 5, it is half way between the two tens, so you always round up to the higher ten)
