Question

How many times smaller is 6 x 10 ^−7 than 4.5 x 10 ^−4?

133
13,333
75
750

Answer 1

Answer:750

Step-by-step explanation: Because it is true

Answer 2

750

Explanation:

first, we will use the fraction- division format
`((x)/(y))`

`x= 4.5` ·
`10^(-4)`

`y= 6` ·
`10^(-7)`

plug in the x and y values

`(4.5* 10^(-4))/(6*10^(-7))`

use the scientific notation

`x= 4.5 * 10^ {-4}=0.00045 \\y=6 * 10^(-7) = (3)/(5,000,000)`

plug in your new x and y values

`(0.00045)/((3)/(5,000,000) )`

Apply the fraction rule
`((x)/((y)/(z) ) =(x * z)/(y) )`

`(0.00045 * 5,000,000)/(3)`

Multiply the numbers

`\frac{2250} {3}`

Divide the numbers

`750`
