Answer:
250%
Step-by-step explanation:
4. Think about it, it would mean that 4 is the result of 0.4 (40%) multiplied by a number. Therefore, you would divide 4 by 0.4. The answer would be 10.
5. To do this, multiply 0.2 by 700. This gives you 140.
6. Think about it, what percent of 25 is 12. Divide 12 by 25, then multiply by 100 and add a percent sign after it. 12/25 is 0.48. Multiply that by 100 to get 48%.
