8a + 3 - a - 2 = 1 - 7a
[Collect the like terms and the subtract the numbers]

=> 7a + 1 = 1 - 7a
[Cancel equal terms on both sides of the equation]

=> 7a = - 7a
[Move variables to the left side and change its sign]

=> 7a + 7a = 0
[Collect the like terms by adding their coefficients]

=> 14a = 0
[Divide both sides of the equation by 14]

=> a = 0

Part A: Using complete sentences, explain how to convert zero point 22 repeating to a fraction. (2 points)
Helen [10]

Answer:

a) \frac{2}{9}

b) Irrational

Step-by-step explanation:

a) Let y=0.\bar2.....(a)

Then 100y=22.\bar2.....(b)

Subtract (a) from (b)

100y-y=22.\bar2-0.\bar2

\implies 99y=22

y=\frac{22}{99}=\frac{2}{9}

b) From part a) 0.\bar2 is a rational number but \sqrt{112}=4\sqrt{7} is an irrational number.

But 0.\bar2\times \sqrt{112} is not a rational number because the product of a rational number and an irrational number is an irrational number.
