Answer 1

Answer:

the answer is 40%

Step-by-step explanation:

theres a easy way to do it: 16/40= 0,4 = 40%

but you could also multiply the denominator so it reaches 100

40 x 2,5 = 100

you do the same thing with the numerators = 16 x 2,5 = 40

and you get this = 40/100 = 0,4 = 40%

I'm sorry for this bad explenation hope you got it!
