What is the lmc of two numbers that have no common factors greater then 1

Luba_88 [7]

We can take prime numbers so they don't have a common factor other than 1.

3, and 5.

So we have to list the multiples to find the LCM

3: 3, 6, 9, 12, 15, 18
5: 5, 10, 15, 20, 25

15 is the LCM of 3 and 5

So, you can notice that if two numbers, lets call them a and b, have no common factor, then $a \times b$ is the LCM.

Hope that helped :)

nirvana33 [79]

7 + 12 + 17 + 22 + 27 = ( 7 + 27 ) + ( 12 + 22 ) + ( 34 / 2 ) = ( 34 / 1 ) + ( 34 / 1 ) + ( 34 / 2 ) = ( 68 / 2 ) + ( 68 / 2 ) + ( 34 / 2 ) = 170 / 2 = 85 .

zachary has coins of the coins 3/6 are nickles, 2/6 dimes, rest are quarters. What is the ratio of zacharies nickles, to dimes t

lesya692 [45]

Answer:

The ratio of zacharies nickels to dimes to quarters is 3 : 2 : 1.

Step-by-step explanation:

Given:

Zachary has coins of the coins 3/6 are nickels, 2/6 dimes, rest are quarters.

Now, to get the ratio of zacharies nickels, to dimes to quarters.

So, as given dimes and nickels we find the quarters to get the ratio:

$\frac{3}{6} -\frac{2}{6}=\frac{3-2}{6} =\frac{1}{6}$ .

Thus, the quarters are 1/6.

Now, getting the ratio of the coins:

Nickels = 3/6 × 6 = 3

Dimes = 2/6 × 6 = 2

Quarters = 1/6 × 6 = 1

Nickels : Dimes : Quarters = 3 : 2 : 1.

Therefore, the ratio of zacharies nickels to dimes to quarters is 3 : 2 : 1.
