Let the first number be x.

Then the second number is x-16

the ratio of these two is 5/6

Spoiler:

so it would be x+x+16=5/6?

no...sorry

you have got two numbers x and x-16

form their ratio i.e. divide one number by another....and then equal it to 5/6

so does it matter what order? would it be x/ x-16 = 5/6?

since you are dealing only with natural numbers, x-16 will be less than x

hence, (x-16)/x=5/6

however solve both ways and see what you get

Im sorry, taking this online class and for college and you are supposed to just do the problems in this workbook but im having problems and there are no directions or anything.... kind fustrating... :[

and continuing with the problem would you then cross multiply?

you got x as 96

the other one is x-16...so you had to add or subtract???

Spoiler:

x-16=96-16...80

ohhh haha okay, thanks so much, very helpful

Read the question properly people...

The ratio of two numbers is . The second number is 16 less than twice the first number.

If we call the first number , then twice the first number is , and 16 less than twice the first number is .


So







.


Therefore



.



So the two numbers are 20 and 24.

For illeatyourxface,
steps are essentialy the same

For me,
I will read questions more carefully

ohhh nowww i see, thanks again, veryyy very helpful
