Answer 2

The expanded form of 3.42 is $\bf 3 + \frac{4}{10} + \frac{2}{100}$

Step-by-step explanation:

Given:

• 3.42

To find:

• Expanded form of 3.42.

Solution:

Concept to be used:

• In expanded form of number, digits are written as sum of their place values.
• Digits have place values before decimal places, from right to left in increasing powers of 10 i.e. 10⁰,10¹,10²,10³...and after decimal places from left to right as decreasing powers of 10 i.e. ${10}^{ - 1} \: {10}^{ - 2} \: {10}^{ - 3}$
• For an example;45.67 is written in expanded form as

$45.67 = 40 + 5 + \frac{6}{10} + \frac{7}{100}$

Step 1:

Write the place values of the digits.

In 3.42

3 is at unit place, it's place value is 3

4 is at tenth place, it's place value is $4 \times {10}^{ - 1}$

or

$\frac{4}{10}$

and

2 is at hundredths place, it's place value is $2 \times {10}^{ - 2}$

or

$\frac{2}{100}$

Step 2:

Write the expanded form of number.

Write sum of all the place value.

Expanded form of 3.42 is

$3 + \frac{4}{10} + \frac{2}{100}$

Thus,

Expanded form is $\bf 3.42 = 3 + \frac{4}{10} + \frac{2}{100}$
