    Answer:

    4 5/6 feet.

    Step-by-step explanation:

    The least common multiple for 2 and 3 is 6, so if we change the denominators to 6, we get Chrystelle’s height as 3 3/6, and her mother is 1 4/6 ft taller than her.

    3 3/6 + 1 4/6= ?

    (Written as an Improper fraction)

    21/6 + 10/6 = 31/6

    31/6 = 4 5/6.

    I hope this helps!

    Answer:

    first make it so the denominator is the same on bothers sides. a common denominator for both is 6 so

    Chrystelle mom: 1 2/3 taller. multiply the fraction by 2/2 so 1 4/6

    chrystelle: 3 1/2 feet tall. multiply the fraction by 3/3 so 3 3/6

    now just add to figure out so

    3 3/6 + 1 4/6 = 4 7/6 which simplifies down to 5 1/6

    so chrystelles mom is 5 1/6 feet tall
