  • 1) Add the total number of the students.

    That would be 300+250 getting 550.

    2)Get the 30% of 300

    That would be

    0.3(300)

    =90

    3) Get the 20% of 250

    That would be

    0.2(250)

    =50

    4)Add the results of steps 2 and 3.

    90+50

    =140

    5) Divide the result of step 1 to the result of step 4.

    140/550

    =approximately 0.2545

    6)Change 0.2545 to percent

    That would be

    25.45%

  • 1) Add 0.30 x 300 and 0.20 x 250. That's the number of students who passed.

    2) Add 300 and 250. That the total number of students

    Divide 1 and 2.

  • I shouldn't tell you this, but here ya go.

    I typed the following into a Google search:

    30% of 300 plus 20% of 250

    I was surprised to see that it gave me the answer!

    Go to the url listed below and you will see the answer.

    I wish I would have had this help when I was in school!

  • divide 50% by the total of girls and boys.
