If 40% of a number is 56, what was the original number?
PLS EXPLAIN
THANK YOU

  • MATH -

    0.40 x = 56

    x = 56/.4 = 560/4

  • MATH -

    the best message I can give to you is this: is over of is equal to percent over 100. the number after is is 56 and the percent is 40. so you put 56/x and set that equal to 40/100 which simplifies to 2/5

    cross multiply the two: 56 * 5 and 2 * x

    write the equation 280 = 2x

    Divide: 280 / 2 = 140

    Answer: 140

    I know this won't help with the specific problem you were having trouble with, but if you ever see a problem with IF, OF AND A PERCENT use this method.

    Hope this helps you in the future

  • MATH -

    56/x=40/100=
    56/x=2/5=
    cross multiply
    56*5=280
    x*2=2x
    280/2=140

  • MATH -

    just do 56/x=40/100 which can be simplified to 56/x=2/5. 56*5=280 and x*2=2x so 280/2 is 140

  • MATH -

    56/x=40/100

    56/x=2/5.
    56*5=280
    x*2=2x
    280/2 is 140

    140
