The numerator that Justin erased is 7
How to determine the value
From the information given;
Let the numerator value by x
We have the expression as;
- whole number part = 45
- Denominator fraction = 9
- Numerator = x
- Number when in improper fraction = 412
We can deduce the numerator as:
9 multiplied by 45 = 405 + x
Let's equate the numerators
405 + x = 412
collect like terms
x = 412 - 405
x = 7
We know that 'x' is the missing numerator value and equals 7
Thus, the numerator that Justin erased is 7
