Question

A

Answer 1

\[30 people \times \frac{ 6 pens }{ 1 people } \times \frac{ 1package }{ 5 pens } \times \frac{ $1.88 }{ 1 package }\]

6 pens=1 people or 6 pens per person
1 package=5 pens or 1 package per person
$1.88=1 package or $1.88 per package
per=divide.

Answer 2

All units cancels out except the $ sign.

Answer 3

Yes.

Answer 4

I was helping someone sorry.

Answer 5

Post it.

Answer 6

\[\frac{ 3.255g }{ mL }=\frac{ 3.255kg }{ L }\]
1000 milligrams=1 grams
1000 grams= 1 kilograms.

Answer 7

Can you solve it now?

Answer 8

What is the formula for density?

Answer 9

The whole process would have to be in conversion?

Answer 10

So what is the unit for density?

Answer 11

d=m/v
so the unit of density is the (unit of m)/(unit of v)
M is mass
V is volume
What are the units for mass and volume?

Answer 12

Yes that works.
So density is g/mL or kg/L

Answer 13

Can you answer this?
The whole process would have to be in conversion (dimensional analysis) ?

Answer 14

Does the whole process need to be like this?
\[\frac{ ? }{ ? } \times \frac{ ? }{ ? } \times \frac{ ? }{ ? }\]
Its a just a yes or no.

Answer 15

Ok, you start with given and make the units cancel until you get Liters by itself.
Similar to what I did earlier.
Since you wouldnt mind trying, show me your dimensional analysis, then I can show you mines.

Answer 16

If you are given unit1 and want to find unit 3 use this
\[\frac{ Unit1 }{ 1} \times \frac{ Unit 2 }{ Unit1 } \times \frac{ Unit 3}{ Unit2 }\]

Answer 17

Notice how unit 1 and unit cancels out?

Answer 18

and unit 2*?

Answer 19

It is supposed to be 123000 mg /1 at the beginning.
That is the given unit.

Answer 20

Oh ok.
I knew that but just didnt write it correctly because I am not actually doing it yet.
But my bad.

Answer 21

Give it one more go and I will post the steps.

Answer 22

100kg is not 1g

Answer 23

\[\frac{ 1236000mg }{ 1 } \times \frac{ 0.000001kg }{ 1mg } \times \frac{ 1000g }{ 1kg }\times \frac{ 1mL }{ 3.255 g } \times \frac{ 0.001L }{ 1mL }\]

Answer 24

3.255 g/mL
can be switched as mL/3.255g

Answer 25

Its supposed to be 1230000 mg not 1236000 my bad

Answer 26

In my opinion without using the dimensional analysis (factor), it is shorter.

Answer 27

Glad to help!

I have to go out for dinner now.
If you still need help, PM me like 2-3 hours.
Good luck on the rest!
