Question

2.5×10^3 times what number is equal to 5×10^6?

Answer 1

To find the number that 2.5×10^3 must be multiplied by in order to equal 5×10^6, divide 5×10^6 by 2.5×10^3. The result is 2×10^3.

Step-by-step explanation:

To find the number that 2.5×10^3 must be multiplied by in order to equal 5×10^6, we can set up the equation:

2.5×10^3 × x = 5×10^6

To solve for x, we can start by dividing both sides of the equation by 2.5x10^3:

x = (5×10^6) / (2.5×10^3)

Next, we can simplify the right side of the equation:

x = (5 / 2.5) × (10^6 / 10^3)

x = 2 × 10^3

Therefore, the number that 2.5×10^3 must be multiplied by to equal 5×10^6 is 2×10^3.

Answer 2

2.5x10^3= 2,500

5x10^6= 5,000,000

Step-by-step explanation:

Here is a great trick that I always keep in mind whenever you are squaring 10 you add that many zeros for example.

10^4= 10000 (there are 4 zeros).
