171÷ 280= 0.61071429 I looked at the digit in the ten thousandths place and it was seven, and seven is over five so the zero is increased by one.

Question 6 c: Round to the hundredths place.

43÷60=0.71666667 I looked at the digit in the thousandths place and it was a six, and six is over five so the digit in the hundredths place increased by one.
