The answer is a = 
Step-by-step explanation:
<em>1. Convert the mixed fraction to an improper fraction</em>
To find the numerator, multiply the denominator by the whole number and add the numerator to it.
The denominator remains the same.
So, 2
will be 
<em>2. Now the equation is,</em>
a - 
a = 
+ a
<em>3. Take LCM on both sides. </em>
For the left side, multiply the first fraction by 
and multiply the second fraction by 
a - 
a = 
<em>4. Solve by making a the subject</em>
=
=
=10+8a
= 10 + 8a
a = 2(10 + 8a)
a = 20 + 16a
a-16a = 20
-15a = 20
a = 
a =
Therefore, the answer is a =

Answer:
Seven numbers.
Step-by-step explanation:
Finding the numbers, which are equal to the sum of two odd number and it has to be single digit number.
Lets look into numbers which are odd and single digit.
1 = 
∴ Sum of the number is 
3 = 
∴ Sum of above number is 
5 = 
∴ Sum of above number is 
7= 
∴ Sum of above number is 
Now, accumlating numbers which are fullfiling the criteria, however, making sure no number should get repeated.
∴ Numbers are: 
Hence, there are total 7 numbers, which are equal to the sum of two odd, one-digit numbers.
