The fraction of the furniture sold that are tables is given by 1/2y / (1/3x + 1/3y)
<h3>Equation</h3>
Let
- number of chairs = x
- Number of tables = y
Number of tables and chairs sold = 1/2(x + y)
= 1/2x + 1/2y
- Fraction of chairs sold = 1/2x
- Fraction of tables sold = 1/2y
Furniture remaining = 1/3(x + y)
Fraction of tables sold = 1/2y ÷ 1/3(x + y)
= 1/2y ÷ 1/3x + 1/3y
= 1/2y × 1 / (1/3x + 1/3y)
= 1/2y / (1/3x + 1/3y)
Therefore, the fraction of the furniture sold that are tables is given by 1/2y / (1/3x + 1/3y)

First add the 8 to both sides, canceling out the 8 in the right and adding it to the 19 on the left, making it 27. Multiplying undoes division so, After that, multiply by three on both sides, canceling out the three on the right and multiply 27 by 3, making it 81.
Speed = distance/time
So speed = 40/10
= 4m/s
