Answer:
I think it is add 11 both sides? If it is wrong i am sooooo sorry
Step-by-step explanation:
let each of the numbers be x :
For every side you just add 90 to your equation. so #4 would be 360-125-125-55=(55)
Answer:
3/14
Step-by-step explanation:
We want to find the ratio of a to b, or a/b
9/17 = 3a/ (a+b)
Multiply each side by 17
17*9/17 =17* 3a/ (a+b)
9 = 51 a/ (a+b)
Multiply each side by (a+b)
9 (a+b) = 51a
Distribute the 9
9a +9b = 51a
Subtract 9a from each side
9a-9a +9b =51a-9a
9b = 42a
Divide each side by b
9b/b = 42a/b
9 = 42a/b
Divide each side by 42
9/42 = a/b
But we can simplify 9/42 because each is divisible by 3, so divide 9 and 42 by 3
3/14 = a/b
Answer:
2:4
Step-by-step explanation:
6
Ratio: 1:2
6/3 = 2
2*1=2
2*2=4
2:4 is the answer
