Question

What percent is of 30 is 40

Answer 1

75% (sorry if it’s the wrong answer I’m dumb)

Answer 2

Answer:  

30/x=100/40

(30/x)*x=(100/40)*x       - you multiply both sides of the equation by x

30=2.5*x       - you divide both sides of the equation by (2.5) to get x

30/2.5=x  

12=x  

x=12

now we have:
