Answer:
20%
Step-by-step explanation:
An equation is 14=x/100*70 or 14=(x%)*70, either one works
solve for x:
- 14=x/100*70
- 14/70=x/100 (Divide each side by 70)
- 1/5=x/100 (Simplify 14/70)
- 100/5=x (Multiply each side by 100 to isolate x)
- x=20 (Simplify 100/5)
- 20% (Rewrite as a percent)
hope this helps!!
