The least common multiple means that the least multiple that the numbers have in common. So you can make a little chart with each of the numbers multiples like so..
3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60,63,66,69,
(Just added 3 each time)
5,10,15,20,25,30,35,40,45,50,55,60,65,70,
(Just added 5 each time)
7,14,21,28,35,42,49,56,63,70,77
(Just added 7 each time)
No we can go and look through the multiples and see what number they all have that's the same! You might have to keep added on multiples until you find some that are alike! You'll eventually reach 105 for each of the numbers and see that that's the first one that they have that's the same!! So 105 would be your least common multiple!

If you buy tomato sauce for $.90 a quart how much does it cost for 5 pints
Dima020 [189]
<h2>Hello!</h2>

The answer is: the price of 5 pints of tomato sauce is $2.25.

<h2>Why?</h2>

To calculate how much does it cost 5 pints, we need to perform a unit conversion with the following  unit relationship:

0.5Quart=Pints

Now, calculating how much is a pint:

\frac{0.9}{quarter}*\frac{0.5Quart}{1Pint}=0.45

A pint is $0.45.

Then, calculating how much are 5 pints:

Price=0.45*NoOfPints=0.45*5=2.25

Hence, the price of 5 pints of tomato sauce is $2.25.

Have a nice day!
