To represent a decimal on a number line, divide each segment of the number line into ten equal parts. E.g. To represent 8.4 on a number line, divide the segment between 8 and 9 into ten equal parts. The arrow is four parts to the right of 8 where it points at 8.4.
The number 0.3 is equal to the fraction \frac{3}{10}, so we need to cut the interval from 0 to 1 into ten equal intervals and locate 0.3 at the third interval marker. in expanded form. Since 6 is in the hundredths place, we need to cut the interval from 0 to 1 into 100 equal intervals.
In order to represent decimals on the number line, we divide the section between two whole numbers as per the places after decimal present in the number to be represented.
To mark 0.75; move three parts on the right-side of zero. To mark 1.50; move six parts on the right-side of zero. To mark -1.25; move five parts on the left-side of zero.
Answer: 0.35 as a fraction is 7/20.
Where would the decimal number 1.5 be on a number line? The decimal number 1.5 has a whole number of 1, which is the number to the left of the decimal. The number 1.5 is halfway between 1 and 2.
To add decimals, write the numbers in a column, and make sure that the decimal points are aligned. To keep the decimal point in your sum, place a decimal point directly below the decimal points in the addends. Align the decimal point in the sum with decimal point in the addends, add a zero if necessary.
2.4 cm can be written as 24/10. So, twenty four tenths is the 24 th part from zero or fourth part from 2. Example 4 : Write 0.1 as tenths and mark it on a number line.
We first see that 1.6 is located between the numbers 1 and 2. Then, the unit length between 1 and 2 is divided into ten equal parts.
The first digit after the decimal point is 4, therefore 0.4 is not a whole number.
The decimal 0.3333 is a rational number. It can be written as the fraction 3333/10,000.
Answer: 0.36 can be expressed as 9/25 in the form of a fraction.

In order to represent 1/2 on the number line, draw the number line and mark a point A to represent 1. Now, divide the gap between O and A into two equal parts. Let T be the point of division. Then, point T represents 1/2.
When asked to add or subtract decimals, the most important step is to line up the decimal points. Step 1: Line up the decimal points so that similar place values are lined up. In other words, the tens place in both numbers should be lined up, the ones place in both numbers should be lined up, etc.
Draw a number line, l. Divide the portion of the number line between 0 and 0.1 in 10 equal parts where each part represent. Mark the 1st point to the right of 0 on the number line. The red point above represent the decimal number 0.01 on the number line.
Convert 0.1 percent to decimal form; 0.1 percent is the same as 0.001. Multiply the decimal form of 0.1 percent by the number you want to find 0.1 percent of. In the example, 0.001 times $40 equals 0.04, or 4 cents.
The decimal 0.4 is equal to the fraction 2/5.
Since, 0.5 being the decimal number, it is not considered to be a whole number. … Since, the value after decimal is equal to 5, then the number is rounded up to the next whole number. Hence, the whole number of 0.5 will be 1.
