You just multiply the numerator with the numerator and the denominator with the denominator.

Example:

2/4*3/5=2*3/4*5=6/20=3/10

Use this formula: V=S/T     V=Velocity (Speed) S=Distance T=Time

So if you know how far an object went and in how much time it went that far you just divide the distance travelled by the time taken.

Example: Mike ran 4 meters in 4 seconds. S/T=V 4/4=1

We know she made 52.50 in 7 hours, so she would then have to make 7 times less money in just one hour. That's 52.50/7, you can use the calculator yourself to get the answer.

I'm assuming you mean 3*(1/10)

3*(1/10)=3/(10/1)=3/10=0,3

The answer is 0,3

When we divide something there are three numbers, you can see an example of a division below.

1

-  =0,25

4

The first number is the one on top of the division, 1, this number is called the numerator.

The second number is the one at the bottom of the division, 4, this number is the denominator.

The third number is the one next to the = sign, 0,25, this number is the quotient.

So the numerator is what you're dividing, the denominator is what you're dividing with, and the quotient is what you get when you divide those things.

Knowing simple latin would help you with this. ''Kilo'' means ''thousand'' in latin, so if something is prefixed by ''kilo'' and ''1'' it means that that there are one thousand of whatever ''kilo'' is refering to. This means there are 1000 grams in a kilogram, and if you need X to produce 1000g you need X/1000 to produce 1g. Hope this helped you understand, don't hesitate to ask further questions if there's something you wonder over.

Or 1 1/4 in fractions 

209+n*14

If I've understood the question right that should be it.

150-n*12,5

You'll find that if n is replaced with the amount of weeks passed you have your balance.

Though a bit about it and I've made a new equation using you guys' advice.

X*(1-5/8+1/6)=110 Minutes 

Etc. etc

X*5/24=110

X=110*24/5

X=528
