Question

How do you convert \[0.42\] into a percentage?

Answer 1

Hint: This is the given number is in decimal form. As we need to convert them into percentage, we will write it in the fraction form. For that we will multiply and divide the given decimal by 100. After getting the fraction now in order to find the percentage we will first just take the numerator as percentage since the denominator is already 100 that is per cent.

Complete step by step solution:
Given is a decimal number \[0.42\]
Now we will multiply and divide it with 100.
\[ = 0.42 \times \dfrac{{100}}{{100}}\]
Multiplying the numerator by 100 we get,
\[ = \dfrac{{42}}{{100}}\]
We know that percent means per 100 so the given ratio has already 100 in the denominator so the numerator is the percentage number.
So \[42\% \] is the correct answer.
So, the correct answer is “\[42\% \]”.

Note: Note that we are not going to shift the decimal because percent means per 100 so the ratio with the denominator 100 gives the numerator as percentage. Decimal is just a sign like a dot. But note that if decimal is not seen in a number it is always at the extreme right end of the number. Here in this case decimal is already present so just shift it.
