A decimal number has two digits to the right of its decimal point. If we round it to the nearest tenth, the result is 18.6. A. 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.

18.64

Step-by-step explanation:

Given that:

The result of a decimal number with two digits to the right of the decimal point is 18.6 when rounded to the nearest tenth.

The maximum possible value of the decimal number is 18.64 ; because the second digit after the decimal point (hundredth) must not be greater than 4, so that when rounded it gives 0.if the hundredth place digit is ≥ 5, it is rounded to 1, which will be added to the tenth place digit which will result in 18.7

For the minimum, it will be 18.55 as a number below 5 in the hundredth pace will be rounded to zero. However, for 18.55, 5 in the hundredth pace will be rounded to 1, to give 18.6

5+2x=a
