Question

11. Sarah is three years older than Ben. If Ben is 16 years old, how old is Sarah? A. XLVIII D. XIII C. XVI B. XIX E. XX ​

Answer 1

Answer: B. XIX

Step-by-step explanation: If Sarah is 3 years older than Ben, she is 3 years older than 16. That means she is 19 years old. In Roman numerals, we need to think of it as she is 10+9 years old.

X represents 10.

IX represents 9 Because...

... in order to represent a number less than ten, we need to think about how much less than ten it is. Since 9 is one less than 10, you write it as IX since a smaller numeral in front of X represents subtraction.

So you combine the 10 and 9 to get XIX.

Answer 2

the answer is B because 19 in roman numerals is XIX
