The steps for dividing fractions are:
Keep
Flip
Change
As in, keep the first fraction the same (we can write 7 as 7/1 to make it a fraction), flip the second fraction upside down, and then change the division symbol to a multiplication symbol. This gives you:
7/1 × 5/6
And to multiply fractions, you multiply across, which means that you do (7 × 5 = 35)/(1 × 6 = 6). Your answer, therefore, is 35/6, or, as a mixed number, 5 5/6. I hope this helps!
The values of x and y are 0.2 and 0.4 respectively.
<em><u>Explanation</u></em>
The given proportions are.....
and
From the second proportion, we will get....
Now, we will plug this into the first proportion. So we will get....
So, the values of x and y are 0.2 and 0.4 respectively.
For this case we have the following polynomial:
We can solve the polynomial by factoring.
We have then:
From here, we clear the solutions of the equation.
Solution 1:
Solution 2:
