Answer:14
Step-by-step explanation:First, you can plug in the numbers, so the equation would look like 126=1/2b(18). Since theres 1/2, 1/2 of 18 is 9, so it would be 126=9b. 126/9=14
Answer:
Step-by-step explanation:
So basically since she used 15 orange balloons she would have to use 10 green balloons
There is infinitely many ratios which are equivalent to 5:9. As we know always we can write divide as fraction, so

. We can multiply nominator and denominator by the any number (but the same) and get another numbers but ratio will be the same, so equivalent.
For example
10:18,
15:27
