Question

2.1 liters of coffee were equally distributed to 30 cups how many millimeters of coffee were in each cup

Answer 1

There are 70 millimeters of coffee in each cup

• Total of amount of liters of coffee = 2.1 liters

Further Explanation

Step 1

Recall, 1 liter = 1000 millimeters  

Therefore to convert 2.1 liter to millimeter, you have:

= $\frac{2.1}{1000}$

= 2100

Hence,

Total amount of liters of coffee = 2100 millimeters

Step 2

Total amount of available cups = 30 cups

To determine how many millimeters of coffee are there in each cup, the total of amount of liters of coffee (2100 millimeters) will be divided by the total amount of available cups (30) i.e. 2100 ÷ 30

Therefore,

= 2100 ÷ 30

= $\frac{2100}{30}$

= 70

Thus, the total amount of coffee in each cup is 70 millimeters

The above mathematical problem is a typical number problem, and it was solved by using a mathematical method, notably, Division.

Division is the process of dividing or splitting numerous significant figures to derive an efficient equal parts or groups.

Furthermore, division is a function of BODMAS, which means, Brackets, Order, Division, Multiplication, Addition, Subtraction.

Answer 2

Answer: 70 ml of coffee in each cup

Step-by-step explanation:

1 liter = 1000 ml

Amount of coffee given = 2.1 liters

$\Rightarrow$ 2.1 liters =  2.1 * 1000 = 2100 ml

Total number of cups = 30

$\therefore$ Amount of coffee in each cup = $\frac{Total\ amount \ of \ coffee}{number\ of \ cups}$ = $\frac{2100}{30}$ =70

∵ Amount of coffee in each cup = 70 milliliters
