The lowest common denomenator is the smallest common factor of them so
20=1 times 2 times 2 times 5
24=1 times 2 times 2 times 2 times 3
the lowest common denomenator is 1
I think the question should have been. what is the greatest common factor (4) or what is the smallest common multiple (120)
Answer:
The answer is 770000000
Step-by-step explanation:
The question mentions that the power 8 is positive then we need to move the decimal point 8 places to the right.
So, the answer is 770000000.
I'd suggest you enclose -1 and 5 within brackets as shown:
4( 2[-1] - [5] ). Do the work within parentheses FIRST: 4( -7 ).
Then multiply as indicated: -28
Explanation:
So, I know a lot of people won't do it this way, but this is how I would do it.
First, multiply each expense by eight (eight for the eight days)
$55 x 8 = 440
$25 x 8 = 200
$129 x 8 = 1032
Next, take the three answers and add them together:
440 + 200 + 1032 = 1672
Lastly, divide 1672 by four (four for the four friends)
1672/4 = 418
There you go! Here is your answer. Each friend paid $418
Hope I helped! :D
I know you have 1 and 3 right but I'm sorry about not knowing the rest.
