0.57
2/5 = 0.4
5/8 = 0.625 so...
5/8, 0.57, 2/5
How I found the decimals..find a number you can multiply by the bottom of the fraction to make it 10, or 100, or 1000, or any 1 followed by multiplying both top and bottom by that number.

A car drives 494 km in 4 hours 45 minutes what is its average speed in kilometers per hour?

Artist 52 [7]

The average speed is 104 kilometer per hour

Solution:

Given that,

A car drives 494 km in 4 hours 45 minutes

To find: Average speed in kilometers per hour

The average speed is given by formula:

$Average\ speed = \frac{distance}{time}$

From given,

Distance = 494 km

Time = 4 hours 45 minutes

We know that,

1 hour = 60 minutes

Therefore,

$45\ minutes = \frac{45}{60}\ hour\\\\45\ minutes = 0.75\ hour$

Thus,

time = 4 hours 45 minutes = 4 hour + 0.75 hour = 4.75 hour

Thus average speed is:

$Average\ speed = \frac{494}{4.75}\\\\Average\ speed = 104$

Thus average speed is 104 kilometer per hour

jack wants to buy the same number of hats for 3 of his friends. he has 57 dollars and each hat cost $5. what is the largest numb

saw5 [17]

Answer: 3

Step-by-step explanation:

You know that he has $57 and 3 friends, so first lets figure out how much money each person gets. To do this, we have to take 57 and divide it by 3. 57÷3= 19.

Now that you know that each person gets $19 and you know that each hat costs $5, all you have to do it divide 19 by 5.

19÷5=3.8.

Since you can't have 0.8 of a hat, each person can only get 3 hats.

I hope this helps. ;)
