Answer:
23.3
Step-by-step explanation:
because you look at the first digit after the decimal point if rounding to one decimal place or the second digit for two decimal places
draw a vertical line to the right of the place value digit that is required
look at the next digit
if it's 5 or more, increase the previous digit by one
if it's 4 or less, keep the previous digit the same
remove any numbers to the right of the line
