If x is the least common multiple of the set {6, 8, 12} and y is the greatest common factor
Anarel [89]

Answer:

12

Step-by-step explanation:

The least common multiple of {6,8,12} is 24. This can be intuitively figured by noting that any multiple of 12 is a multiple of 6 and that 12 is 1.5x larger than 8. That means we only have so multiple 12 by 2 and 8 by 3 for them to be equal. The GCF of {20,42,72} is 2 as the prime factorization of 20 is 2x2x5 and 42 is 2x3x7. That means even without having to check 72 (which is clearly even so 2 is a factor), we know that 2 is the greatest common factor that they could share. So X/Y = 24/2 = 12

Divide. Reduce the answer to lowest terms. 3/4 ÷ 1/3
Slav-nsk [51]

Answer:

9/4

Step-by-step explanation:

When you divide by a number, whole number or fraction, it's exactly like multiplying by its inverse.

Like if you divide 4 by 2,  you can easily express that has 4 * 1/2.

In the same manner, when you divide 3/4 by 1/3, you can say that you're multiplying 3/4 by 3/1

The result of 3/4 * 3/1 = 9 / 4

Which you cannot simplify because 9 and 4 don't have any common factors (other than 1).  The only other way to express it would be 3²/2² or (3/2)²

Constance's car has a 12-gallon gas
antiseptic1488 [7]

Answer:

7.5 hours

Step-by-step explanation:

Constance's car has a 12-gallon gas tank.

She can travel 25 miles on one gallon of gas, so she can travel

25\cdot 12=300 miles using all gas from the tank.

Constance begins with a full tank of gas and drives at a constant rate of 40 miles per hour.

So, Constance can drive for

300 : 40=7.5 hours.

On Eduardo's workbench are the following
Maurinko [17]

Answer: 2/5

Step-by-step explanation:

Number of cans of red paint = 3

Number of cans of blue paint = 5

Number of cans of green paint = 8

Number of cans of yellow paint = 4

Total number of cans of paint = 20

The probability that Eduardo will

choose a can of red paint or a can of blue will be:

= P(red) + P(blue)

= 3/20 + 5/20

= 8/20

= 2/5

The probability is 2/5.
