What is the greatest common factor of 42 and 96? A
2

B
3

C
6

D
8

C

Step-by-step explanation:

To solve this question, you must know what a factor is. A factor of a number, divides the number without a remainder.

Knowing this, you need to factor out the numbers

Factors of 42 are:  (1*42), (2*21), (3*14), (6*7)

Factors of 42 In a list: 1, 2, 3, 6, 7, 14, 21, and 42.

Factors of 92 are: (1*96), (2*48), (3*32), (4*24), (6*16), (8*12)

Factors of 92 in a list: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48 and 96.

The greatest number that both list of factors have in common is 6.

Therefore the answer is C

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
