23.294 to 1 decimal place

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
