(-10/10) - (-18/9)
(-1)-(-2)=1
THe answer is 1.
using pemdas sovle what's in parenthesis first:
(-10/10) = -1
(-18/9) = -2
so -1-(-2)= 1
Thank you so much.
To subtract fractions, you need to have a common denominator.
In this case, the least common multiple (LCM) of 10 and 9 is 90.
Next, you need to convert both fractions to have a denominator of 90.
For the first fraction, -10/10, you multiply both the numerator and denominator by 9 to get -90/90.
For the second fraction, -18/9, the denominator is already 9, so you just multiply the numerator by 10 to get -180/90.
Now that both fractions have a common denominator, you can subtract them.
(-90/90) - (-180/90) = -90/90 + 180/90
To add or subtract fractions with the same denominator, you simply add or subtract the numerators while keeping the denominator the same.
-90 + 180 = 90
Therefore, the result is 90/90, which simplifies to 1.
