Choose two numbers from this list: 3, 4, 6, 12. Explain the difference between finding the greatest common factor and the least
vivado [14]

Answer:

Please check explanations for answer

Step-by-step explanation:

Let us choose 4 and 6

When we talk of the greatest common factor, we mean the highest number that is a factor of both numbers

The factors of 4 are 1,2,2 and 4

Factors of 6 are 1,2,3 and 6

So as we can see the only common factors to both are 1,2 but the highest here is 2

The least common multiple refers to the smallest number which divides 4 and 6 at the same time without leaving a remainder

Multiples of 4 are 4,8,12 , 16,20 •••••

multiples of 6 are 6,12,18,24

As we can see, the lowest common number to both is 12

You have to divide 450 and 1800 in order to find the ratio of money spent out of the income on food, then multiply that decimal by 100 in order to convert into a plausible percentage; in this case, it is 25%.

An elevator travels 310 ft in 10 seconds at that speed how far can this elevator travel in 12 seconds explain your reasoning
marta [7]

Answer:

<u>372 ft</u>

Step-by-step explanation:

This can be solved through cross multiplication.

310ft/10sec= x/12sec

Multiply the values across from each other. (A good way to know you've done it properly is if the numbers you multiplied are in different measurements. ex: 1 value is feet,  the other is seconds)

310 x 12 = 3720

Divide by the remaining value.

3720 / 10 = 372

Will give Brainliest! if right!

The answer is B 36 because the chance of you grabbing a white or black is 12/15 meaning if you pulled 15 marbles, most likely 12 of them are white or black. so, because 15 goes into 45 3 times, you multiply 12/15 by 3 getting 36/ 45 meaning you will mostly pull 26 black or white marbles.
