Final answer:
To divide decimals, you do not need to multiply the dividend and divisor by the same number. Simply divide the dividend by the divisor.
Step-by-step explanation:
To divide decimals, you do not need to multiply the dividend and divisor by the same number. Instead, we can simply divide the dividend by the divisor. In this case, we want to divide 2825 by 0.7. So, the answer is:
2825 ÷ 0.7 = 4035
Therefore, neither Elon nor Rachel is correct. We can directly divide 2825 by 0.7 without any additional multiplication.
