1. We assume, that the number 432 is 100% - because it's the output value of the task.
<span>2. We assume, that x is the value we are looking for. </span>
<span>3. If 432 is 100%, so we can write it down as 432=100%. </span>
<span>4. We know, that x is 45% of the output value, so we can write it down as x=45%. </span>
5. Now we have two simple equations:
1) 432=100%
2) x=45%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
432/x=100%/45%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 45% of 432
432/x=100/45
<span>(432/x)*x=(100/45)*x - </span>we multiply both sides of the equation by x
<span>432=2.22222222222*x - </span>we divide both sides of the equation by (2.22222222222) to get x
<span>432/2.22222222222=x </span>
<span>194.4=x </span>
x=194.4
<span>now we have: </span>
<span>45% of 432=194.4</span>
For 4. (Apples to balloons) it is really simple. All you have to do is count the amount of balloons and apples and turn into a ratio, which is a basically a fraction. The answer for that would be 4:2
For the other 4, im not sure what the answer is as i cant really see it that well.
3 and 3 are pretty easy too. All you need to do is find a common factor. For the first number 3, 6 and 8 can both be divided by 2. The will turn it in 3/4, which is as simple as the number can get. The next one can also be divided by 2, which will turn it into 5/7. Once again, this is as simple as it can get.
Answers:
3. 3/4
3. 5/7
4. ? (couldn't see it)
4. 4:2
Answer:
Step-by-step explanation:
Given
___ 
Required
Fill in the gap
First, we need to solve
So:
___
becomes
3.162 ___ 5
3.162 lies between 3 and 4
So, we can say that
lies between 3 and 4
Since:
3.162 is less than 5, the gap can be filled with <.
So, we have: 3.162 < 5
