we are asked to round off 5.67 to the nearest tenth
tenth is the number to the right of the decimal point
so when we are rounding off 5.67, we have to first check the digit in the hundredths place. hundredths place is to the right of the tenths place.
if the digit in the hundredths place is equal to or greater than 5, then we add 0.1 to the number, if the digit in hundredths place is lesser than 5, then no change is done.
digit in hundredths place is 7, this is greater than 5, therefore we add 0.1 to 5.6
5.6 + 0.1 = 5.7
answer is 5.7
