Answer:
Step-by-step explanation:
two birthday gifts n each costs $12.50 so 12.50x2 = $25
sales tax was 6.75% on $25 = 25x6.75/100 = $1.69
total cost including tax = 25+1.69 = $26.69
You first need to make sure the denominators are equal, then when they are, you can add/subtract the numerators. Then you can place the result over the common denominator.
I hope this helps! :)
