Mixed number or mixed numeral
This already is a mixed numeral.
Convert it to what? Eight and 3/4 <- that is currently in mixed form, what form are you trying to get it in?
You convert the mixed numeral into an improper fraction. Now subtract the improper fraction from the whole number by putting the whole number over 1.
Twelve over twelve as a mixed number can't appear as a mixed number like one and three fourths, so twelve over twelve equals a whole, or AKA, 1. There's your answer.
No.
Twelve over seven as a mixed number = 15/7
No, the sum could be a whole number. 1 and 2/3 + 3 and 1/3 = 5
The answer depends on what you wish to convert into a mixed fraction.
