Read the following decimal fractions. 4.86

Short Answer

Expert verified
Four point eighty-six.

Step by step solution

01

Identify the whole number part

Look at the number before the decimal point. In the number 4.86, the whole number part is 4.
02

Identify the decimal part

Look at the numbers after the decimal point. In 4.86, the decimal part is 86.
03

Read the whole number part

Read the whole number part as a normal number. Here, 4 is read as 'four'.
04

Read the decimal part

Read the decimal part as a separate number. Here, 86 is read as 'eighty-six'.
05

Combine the whole number and decimal parts

Combine the readings by adding the word 'point' between them. Therefore, 4.86 is read as 'four point eighty-six'.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Whole Number Part
When reading decimal fractions, the whole number part is the segment before the decimal point. This part is similar to reading any other whole number, straightforward and easy. For instance, in the decimal 4.86, the whole number is simply 4. This means it is read just as 'four'. Remember, the whole number part provides the initial context of the decimal fraction. It gives you an idea of where the number stands on the number line in terms of complete units. Always start with the whole number part when reading a decimal since it lays the foundational understanding of the overall value of the decimal.
Decimal Part
The decimal part follows the decimal point and comprises the digits to the right of the point. It is distinct from the whole number. In the example of 4.86, the decimal part is 86. To read it, you must view these digits as a complete number rather than individual ones. This means 86 is read as 'eighty-six', not 'eight six.' The decimal part shows the value of the fraction of a whole that the decimal represents. Understanding and reading the decimal part correctly is crucial as it enhances your comprehension of the number's finer, smaller values.
Combined Reading
Combining the whole number part and the decimal part is the final step to properly read a decimal fraction. Once you understand the individual parts, you can merge them with ease. To do this, insert the word 'point' between the whole number and the decimal parts. For instance, in 4.86, you first read the whole number part as 'four', then say 'point', followed by the decimal part 'eighty-six'. Therefore, 4.86 is articulated as 'four point eighty-six'. This method of combining ensures the decimal is read accurately and understood clearly. By breaking it down into manageable segments and then combining them, you simplify the reading process of any decimal fraction.
