Adecimal number has two digits to the right of its decimal point. if we round it to the nearest tenth, the result is 18.6 what is the maximum possible value of this number? use words and the number line to explain your reasoning. include the midpoint on your number line. what is the minimum possible value of this decimal? use words, pictures or numbers to explain your reasoning.

18.6?if it is rounded to 18.6, the digit in the ones place would have to be 18.55 thru 18.59...the lowest being 18.55 and the highest being 18.59.

Reasoning : 18.59when rounded to the nearest tenthsu look at ur number in the tenths place, it is 5now look at ur number to the right of it...if that number is 5 or above, u round the 5 to a 6...but if that number is 4 or below, the number would remain a 5.

Examples :
18.55 rounded to the nearest tenths = 18.6 (because the number to the right of 5 is 5, so we round up to 18.6
18.54 rounded to the nearest tenths = 18.5(because the number to the right of the 5 is 4so we round it to 18.5
