Answer:
1/10 or 0.1
Step 1:
Add your one over so it becomes
4/5x=1+7 or 4/5x=8
Step 2:
You want to divide you 4/5 and your 8 together to find your x. When dividing by fractions you can just multiply the opposite (or the reciprocal)
So you would multiply
4/5 * 1/8
When multiplying fractions you just multiply across so
4*1
5*8
4/40
Step 3:
Simplify your fraction
4/40 breaks down to 1/10 because you can divide both numbers by 4
So x-1/10 or 0.1
