24 out of the 30 students in

2 answers:

6 0

So if 24 out of the 30 kids rode the bus to school, that means that only six kids did not ride the bus.
We can set up a fraction with this situation! The denominator will be 30 because that is the total amount of kids overall.
Since we are trying to find the number of kids who DID NOT ride the bust, we have to subtract 30 from 24(30-24) to get how many kids did not take the bus.
This would give us a fraction of 6/24. Then we have to simplify it. It can be divided by 6 to the numerator and denominator giving us
1/4

The answer is 1/4 of students did not ride the bus.

Can I get true brainliest or a heart? Thanks, if you need more help please contact me in instagram.

Answer: 1/5

Step-by-step explanation: 30-24=6 and there is 30 students in Mr. Willow's class so 6 out of 30 students don't ride the bus. Sumpllify it and get 1/5 Find the GCD (or HCF) of numerator and denominator

GCD of 6 and 30 is 6

Divide both the numerator and denominator by the GCD

6 ÷ 6

30 ÷ 6

Reduced fraction:

1 /5

A car traveled 330 miles during a 5½ hour period. If the speed at which the car traveled can be represented in the equation d=rt

Alina [70]

Answer:

The car was travelling at a speed of 60 miles per hour.

Step-by-step explanation:

Given:

Distance traveled = 330 miles

Time Period = $5 \frac12\ hr$

we need to find the speed of the car .

Solution:

Time Period = $5 \frac12\ hr$

Now we can say that;

$\frac12\ hr =0.5\ hr$

So Time period = $5+0.5 =5.5\ hr$

Now we know that;

Distance traveled $(d)$ is equal to Speed $(r)$ multiplied by Time Period $(t)$ .

framing in equation form we get;

$d=rt\\\\330 =r\times 5.5$

Dividing both side by 5.5 we get;

$\frac{330}{5.5}=\frac{5.5r}{5.5}\\\\r = 60\ mi/hr$

Hence The car was travelling at a speed of 60 miles per hour.

The ratio of blue marbles to red marbles in a box is 3 to 2. if there are 12 blue marbles in a box then how many red marbles are

valkas [14]

The answer is: 8 red marbles!

This is because the equation can be written out like this
Blue to red - 3:2
Now it is, blue to red - 12:x

We have to think, what is the difference from the first equation to the second. We know the number 3 times 4 = 12, so we would do the same for the red, 2 times 4=8

If this helped, give me brainliest :)
