-0.9

Practice makes perfect

We want to write the given fraction as a decimal number. - 9/10 Let's ignore the negative sign for just a moment. We can expand the numerator and the denominator of the fraction to write it as a decimal. Let's do it!

9/10

ExpandFrac

a/b=a * 10/b * 10

9* 10/10* 10

Multiply

90/100

CalcQuot

Calculate quotient

0.9

We found that 910 written as a decimal is 0.9. Therefore, - 910 written as a decimal is - 0.9.
