assume x > 0.
what percent of 8x is 5x?
i know that the equation is
5x/8x = p/100
and i have to multiply both sides by 100, but i'm not sure how to multiply 100 * 5x / 8x?
what is 65% of 80x?
again, i know that the equation is
a/80x = 65/100
and i have to multiply both sides by 80x, but i'm not sure how to multiply 80x * a / 80x and 80x * 65 / 100
what percent of 8x is 5x?
---> 5x/(8x) * 100% , the x's cancel
= (5/8)(100)%
= 62.5%
65% of 80x
= .65(80)x
= 52x
Don't make things more difficult than they are
lets admit we all are sixth graders who did big ideas book for math 7/8
I had this question too.
I know its late but all you do is...
5x/8x=p/100
multiply cross products: 100(5x)=500x and 8xp
divide by 8x and you get p=52x
Have a good day!!!
