Question

How do you write -0.70 as a fraction?

Answer 1

Hint: We have to solve this problem with the help of fraction and decimal. We know that in a whole number the fractional part is denoted with the decimal point. Also, we have a minus sign in our problem so we have to take care of that as well. So, let’s see how we can solve this problem.

Complete step by step solution:
We have - 0.70 which we need to convert into a fraction.
So, as there are two digits after the decimal point, therefore
 $-\dfrac{0\not{.}70}{100}$
 $=-\dfrac{7}{10}$

Therefore, -0.70 = $-\dfrac{7}{10}$ in fraction.

Note:
For the given problem we have to find the fraction of the decimal. To distinguish from another fraction, we can simply note that the denominator is smaller than the numerator, so it is a proper fraction. We also need to check if the proper fraction is in the lowest form or not. In this question, we have to make the fraction in the lowest form. Other types of fractions are improper, mixed, like, unlike, and equivalent fractions. Moreover, we have kept the minus sign as it is because the minus sign cannot be canceled at any point in the solution.
