Find Z for the following proportion

Mathematics
2 answers:

This is the simplest proportion i have seen.
This is how we do it:
\frac{z}{7} = \frac{1}{7}
The answer surprisingly is obvious, z = 1
But we can still do cross multiplication

7z = 7
Divide by 7 to isolate z

\frac{7z}{7} =  \frac{7}{7}
7 and 7 cancels out
z = 1

Answer:

1.5

Step-by-step explanation:

The mean is 2.5

1-2.5=1.5

5-2.5=2.5                  This is the absolute distance from the mean  

3-2.5=0.5

1-2.5=1.5

1.5+2.5+0.5+1.5=6

6/4=1.5

Hope this helps!

If you need more help there are websites such as that have algebra calculators if you need more help!

Just in case you didn’t know, you can also use photomath, for math problems. They give you the answer and they also include the steps. You can do that instead of waiting for someone to answer here, it’ll be alot faster:)

Is the least common multiple of a pair of numbers ever less than both numbers
nadezda [96]

well It never could be less than both numbers. the LCM of 2 numbers shd either be greater than the 2 numbers .... or the answer should be equal to either one of the numbers ...

lets see some examples to prove this conclusion:

now, lets find the LCM of 2 and 6 ... so if we do it ... we get the answer 6 .. which is ..as we said equal to one of the numbers

another example : 5 and 7 ... in this ... if we do it .. .we get the LCM as 37 ... which is greater than both the numbers

another case where both the numbers are same ....

where we need to find the LCM of 7 and 7 ... the answer will be 7 itself .....
