Find a common multiple in between the denominators.
10 and 3 and 5 -> the least common multiple is 30.
Change all the denominators to 30 by multiplying the top and bottom by the same number.
9/10=27/30
1/3=10/30
1/5=6/30
Subtract!
27/39-10/30-6/30=11/30
The answer is 11/30
Hope this helps!

Step-by-step explanation:
<em>x = 4</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>use </em><em><u>Thales theorem</u></em>
<em>x/(x + 8) = 4/12</em>
<em>12x = 4x + 32</em>
<em>12x - 4x = 32</em>
<em>8x = 32</em>
<em>x = 32 : 4</em>
<em>x = 4</em>
<em />
<em>4/(8 + 4) = 4/12</em>
<em>4/12 = 4/12 (true)</em>
<em />
<em>Good luck !</em>
