Subtract. 9,002,000−5×106 what property of equality do i use to solve this and how do i solve it?

4.002 * 10^6

Step-by-step explanation:

9,002,000 −5×10^6

re write 9002000 in scientific notation

9.002 * 10^6 - 5 * 10^6

9.002 * 10^6

-5         * 10^6

4.002 * 10^6

You can't use a property of equality since there is no equals sign

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
