Answer:
20% or . 2
Step-by-step explanation:
To understand how to solve, you have to understand that 14 can go into 70 (X) amount of times, this is how percentages work. To find how many times 14 goes into 70, you divide 14/70 = .20
Since 14 is 20% of 70, you can multiply 14 by 5 and it equals a 100% of 70, or just 70 itself. Hope this helped
