Approximately how many times greater is 2.3x10^-4 than 1.15x10^-8 ?
a: 115
b: 200
c: 11,500
d: 20,000

2.3 × is 20,000 times greater than 1.15 ×

Step-by-step explanation:

Given as :

The first number= x = 2.3 ×

The second number= y = 1.15 ×

Let The first number is z times greater than second number

i.e x = z × y

Or, z =

Or, z =

Or, z = 2 ×

∴  z = 20,000

So,The first number is 20,000 times greater than second number

Hence, 2.3 × is 20,000 times greater than 1.15 × . Answer

probably the last option
