Lcm is between 100 and 200 and their greatest common factor is 64

The possible numbers are,

64 and 128 or 64 and 192

Step-by-step explanation:

Given,

The greatest common factor of two numbers is 64,

Let first number = 64x and second number = 64y

Where,

GCF(x, y) = 1,

Now, LCM( 64x, 64y) = 64xy,

According to the question,

100 < 64xy < 200

⇒ 1.5625 < xy < 3.125

⇒ xy = 2 or 3   ( ∵ xy must be a whole number )

If xy = 2,

⇒ x = 1, y = 2 or x = 2, y = 1

Thus, the numbers are 64 and 128.

If xy = 3,

⇒ x = 1, y = 3 or x = 3, y = 1

Thus, the numbers are 64 and 192.

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
