A pitcher of water contains 1/4 liters of water. The water is poured equally into 5 glasses.

vladimir2022 [97]

Answer:

a. 1/20 liters in each glass.

b. 50 ml in each glass.

Step-by-step explanation:

a. To find how many liters are in each glass, you have to divide the 1/4 liters by 5 glasses, because the water is poured equally.

$\frac{1}{4}\:\div \frac{5}{1}$

Using the division properties of fractions:

$\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}$

$\frac{1}{4}\times \frac{1}{5} =\frac{1\times \:1}{4\times \:5} =\frac{1}{20}$

b. Use the rule of three to convert from liters to milliliters.

1 l = 1000 ml

1/20 l = x ml

Now, multiply 1/20 l by 1000 ml and divide by 1 l to obtain x.

$x =\frac{ \frac{1}{20}\times 1000 }{1} = \frac{1000}{20} = 50$

5120 m/s converted to km/h

tensa zangetsu [6.8K]

Answer:

18,432 Km/ h

Step-by-step explanation:

Using the conversions

• 1 Km = 1000 m

• 1 hour = 60 × 60 = 3600 seconds

Then

5120 m = $\frac{5120}{1000}$ = 5.12 Km and

5.12 Km × 3600 = 18,432 Km / hour
