Make these fractions have the same denominator. When in doubt just multiply the fractions by each other’s denominator. Whatever you do to the top you must do to the bottom.
1/3 x 100/100= 100/300
87/100 x 3/3 = 261/300
your number line is 100/300-261/300. One acceptable answer would be 200/300, which is reduced to 2/3.
ANSWER: 2/3
