Answer:
Step-by-step explanation:
Let h be the number of hats Elliott makes and s be the number of scarves she makes.
Each hat uses 0.2 kilograms of yarn and each scarf uses 0.1 kilograms of yarn. Elliott wants to use twice as much yarn for scarves as for hats. This is expressed as
h = 2s
The total number of hats and scarves that she wants to make is 20. This is expressed as
h + s = 20
Therefore, the system of equations that represents this situation are
h = 2s
h + s = 20
Hello,
Here is your answer:
The proper answer to your question is "5/12".
Here is how:
All you have to do is subtract 4/6 and 1/4:
4×2=8
6×2=12
-
1×3=3
4×3=12
8-3=5
Your answer is 5/12!
If you need anymore help feel free to ask me!
Hope this helps!
First make each fraction into an improper fraction
2 2/3 = 8/3
1 5/6 = 11/6
Next, make the fractions have same denominators. Note, that what you do to the denominator, you do to the numerator.
8/3(2/2) = 16/6
Add
16/6 + 11/6 = 27/6
27/6 = 4 3/6 = 4 1/2
4 1/2 is your simplified answer
hope this helps
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>
