how many cups is 1080 ml in fraction form?

Question

anonymous · Answer

Depends on the Cup size, if it's 250ml, then it's $$\frac{ 1080 }{ 250 } ,$$ But the aim of reducing fractions down further, is to get them to the smallest fraction possible by using numbers that both the top/bottom or numerator/denominator will divide by evenly, with no decimals. 

The easiest one's are /2 /3 /4, Let's test this here. $$\frac{ 1080 }{ 250 } /2 = \frac{ 540 }{ 125 }$$ $$\frac{ 1080 }{ 250 } /3 = \frac{ 360 }{ 83.3 }$$ ^ Decimals so we won't use this.

$$\frac{ 1080 }{ 250 } /4 = \frac{ 270 }{ 62.5 }$$
^ Decimal so we won't use this.

Let's go back to and see if we can make that even smaller. $$\frac{ 1080 }{ 250 } /2 = \frac{ 540 }{ 125 }$$ 
$$\frac{ 540 }{ 125 }/5=\frac{ 108 }{ 25 }$$As you can see, it doesn't look like this can be reduced any further, so your final answer is 108/25.

For a standard U.S. "cup" of liquid  it's going to be$$1080\cancel{mL}*\frac{1cup}{236.588\cancel{mL}}=?\space cups$$

Obviously you can reduce the final answer there.

Another way to think about it is:$$\frac{ X }{ Y }/A$$ X is your initial value the one you want to divide into the Y value, in this case a container. Then you dived X/A and Y/A, Your A value is whatever is the largest number that X/Y can divide into evenly. (No decimals) 

In your example earlier X= 1080 and Y = 250, A was 2 ( At first ) then A was 5. I like to reduce sometimes by an initial number.

If you notice, $$\frac{ 1080 }{ 250 } /10 = \frac{ 108 }{ 25 },$$Which was the same result as dividing it by 2 then by 5, and as you already have probably noticed 2x5=10, the value that 1080/250 can divide into the most evenly and reduced down to the most.
