at a restaurant the ratio of kids meals sold to adults meal was 5:4. if there were 20 kids meals sold, what is the combined amount of kids and adults sold meals sold?

Answers

Answer 1
Answer: I would set up a proportion:

(20)/(x)=(5)/(4)

The proportion basically says, "if there are 5 kids meals for every 4 adult meals, that means 20 kids meals would mean x adult meals."  Just cross multiply and then solve for x:

(20)/(x)=(5)/(4)\n5x=80\nx=16

That means there are 20 kids meals sold and 16 adult meals sold, so the result is:

36 meals in total.
Answer 2
Answer: 5x=20\ \ \ \ | divide\ by\ 5\n\nx=4\n\n5x+4x=9x=9*4=36\n\nCombine\ amount\ is\ 36.

32:__=12:24
whats the answer

Answers

the answer would be 64 since the equation is 32:_=12:24, and 12:24 simplified would be 1:2, 32 times two would be equal to 64, making the ratio complete and correct.
Hope this helps

32: __ = 12 : 24

32 divided 3 = 12

so that means __ divide 3 should be 24

24 * 3 = 72

Plug it in:

32:72 = 12: 24

Does 32:72 simplify to 12:24? Yes, so it should be your answer... unless the question is asking for something else.
