Answer: -3-5 / 5
Step-by-step explanation
To write as a fraction with a common denominator, multiply by 5/5.
-3/5 + * 5/5
Then combine fractions, so that the numeratiors over the common denominator.
-3 + 5 /5
Simplify with factoring out.
Rewrite -3 as -1 (3). Next factor -1 out of 5 . Then facotr -1 out of -1(3) - (-5
). After that move teh negative in front of the fraction.
Exact Form: - 3-5 / 5
Decimal Form: 1.13
