Posted by on .

there are 400 students at smith Elementary school 1/4 of the students are in fourth and fifth grade, 1/10 of the students are in grade 3, 2/8 are in second grade and 2/5 are in first grade . How many kids are in each grade?
(4th and 5th have an equal amount)

  • MATH - ,

    so 1/4 in fourth and 1/4 in fifth
    grade 1 = 2/5 * 400 = 2 * 80 = 160
    grade 2 = 2/8 * 400 = 2 * 50 = 100
    grade 3 = 1/10 *400 = 1 * 40 = 40
    grade 4 = 1/8 * 400 = 1 * 50 = 100
    grade 5 = 1/8 * 400 = 1 * 50 = 100

    grade 2 is 2/8 which is 1/4 by the way, sme as grades 4 and 5
