This question is worded a little funny...
I think they might be asking "What percent of 544 is 544-121?"
Here's how you would solve it if that's what you mean:
$${\mathtt{544}}{\mathtt{\,-\,}}{\mathtt{121}} = {\mathtt{423}}$$
So really, our new question is "What percent of 544 is 423?"
$${\frac{{\mathtt{423}}}{{\mathtt{544}}}} = {\mathtt{0.777\: \!573\: \!529\: \!411\: \!764\: \!7}}$$
Or rounded up to the nearest percent, about 78%
Your question doesnt make sense!
And if u want to subtract 554 and 121 then this is the answer
554 - 121 = 423 ANSWER
