In a certain fraction, the denominator is less 7 than the numerator. If 3 is added to both the numerator and denominator, the resulting fraction is equal to 15/8 . Find the original fraction.

original fraction =12/5

Step-by-step explanation:

let x = numerator

therefore

   x+3/x-7+3 =15/8

    x+3/x-4 =15/8

      8(x+3)=15(x-4)

      8x+24=15x-60

       84=7x

        84/7=x

        12=x

therefore original fraction = 12/5

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
