Answer:
x = 3/10
Step-by-step explanation:
−1/2 − (−4/5) = x
First, switch sides.
x = −1/2 − (−4/5)
You are subtracting a negative number. Subtracting a negative number means add a positive number.
x = -1/2 + 4/5
Now you are adding two fractions, so you need a common denominator. The LCD of 2 and 5 is 10.
x = -5/10 + 8/10
your answer might be 1.1
You see you have to divide it so it will be -1 divided by 2-(- 4 divided by5)=x so if we do x - those all our answer will be 1.1 your welcome I hope that helps
