Write the following improper fractions as mixed number or a whole number 28/3
kolbaska11 [484]

Answer: 9 and 1/3

Step-by-step explanation: To write an improper fraction as a mixed number, we divide the denominator into the numerator.

In this case, we divide 3 into 28.

3 divides into 28 nine times with a remainder of 1.

In other words, 9 wholes and 1 out of 3.

if i have a jar 600ml and i add the water from this measuring cylinder to 3.6 liters of water.how much water do i now have altog
Ber [7]

If the cylinder already has 3.6 Liters in it, adding 600 mL would make the cylinder have 4.2 Liters of water in it.

We know this because 600 mL converted to Liters equals 0.6 L. So 3.6 L + 0.6 L = 4.2 Liters.
