We want to write the given mixed number as a decimal.
- 2 1718
We will first rewrite it as a fraction. Let's also ignore the negative sign for just a moment.
We found that 2 1718 is equal to 53 18 when it is written as a fraction. This means that we actually want to find the quotient 53÷ 18. We find the quotient by dividing the numerator of the fraction by its denominator. Let's do it!
We can see that the pattern starts to repeat itself after a few steps. This means that the decimal is a repeating decimal. We can write it using bar notation. Remember, the bar goes over the decimal part that repeats itself.
2.944444... = 2.94
We found that 5318 written as a decimal is 2.94. Since we previously found that 2 1718 is equal to 5318, we can say that 2 1718 written as a decimal is 2.94.
2 1718= 5318=2.94
Therefore, - 2 1718 is equal to - 2.94.
