Answer:
50
Explanation:
First, we need to write this as an equation.
1. the number is x.
2. the value of 10% is 10/100 = 1/10x
3. we can write this as x + 1/10x = 55
4. since the denominator of the fraction on the LHS is 10, we can simplify to 10/10x +1/10x=55.
5. 11/10x=55
6. Multiply by 10 on both sides to get rid of the denominator.
10 * 11/10x = 55 *10
11x = 550
7. Divide both sides by 11 to get the answer.
x = 50
The number is 50.
Hope this helps!
