Write twenty-seven and ninety-one thousandths in decimal notation​

Answer 1

Twenty-seven and ninety-one thousandths in decimal notation is written as 27.091, with the whole number to the left of the decimal point and the fractional part to the right.

Step-by-step explanation:

To write twenty-seven and ninety-one thousandths in decimal notation, you place the whole number part of twenty-seven to the left of the decimal point. Then, you place the fractional part, ninety-one thousandths, to the right of the decimal point, ensuring that the last digit, one, is in the thousandths place. Therefore, the number in decimal notation is 27.091.

Answer 2

To convert 27 and 91 thousandths to decimal, keep 27 as is and express 91 thousandths as 0.091. The combined result is 27.091.

Step-by-step explanation:

To convert the fraction 91 thousandths to a decimal, divide 91 by 1000 because a thousandth is 1/1000. This division yields 0.091. Then, add this value to 27 to get 27.091.

When you have a number like 27, it represents whole units. Adding a decimal portion, 0.091, accounts for the fractional part, in this case, 91 thousandths. The process involves recognizing that each decimal place value represents a power of 10.

So, when converting a fraction to a decimal, divide the numerator (91) by the denominator (1000) to obtain the decimal equivalent of the fraction. The decimal point is the crucial marker that separates the whole number from its fractional parts.

In this case, 0.091 is the fractional part that represents the value in thousandths. Understanding how decimals correspond to fractions helps in interpreting and manipulating numbers, making it easier to express them in different forms for calculations or comparisons.
