I forgot how to change a decimal to a fraction.
i need to change to a fraction the following
-2.5
-2 and 5/10
or -25/10 = -5/2
thank you ...and i have to say duhhh to me.
No problem! To change a decimal to a fraction, follow these steps:
1. Identify the place value of the last digit after the decimal point. In this case, the last digit is 5, which is in the tenths place.
2. Write the decimal as a fraction with the decimal place value as the denominator. Since 5 is in the tenths place, the denominator will be 10.
So, for -2.5, it can be written as -2 and 5/10, which simplifies to -2 and 1/2 or -2.5 as a mixed number.
Alternatively, you can simplify it further by dividing both the numerator and denominator by their greatest common divisor, which in this case is 5. Dividing 5 by 5 gives 1, and dividing 10 by 5 gives 2. So, -2.5 can be simplified to -5/2.
I hope that helps! Let me know if you have any more questions.
