Answer:
+5
Step-by-step explanation:
you add five to each number to get the next
You want to isolate the x first.
Subtract 3/7 from both sides.
That will result in -2/3x = 1/2 - 3/7
(common denominator = 14)
-2/3x = 1/14
Find x by multiplying both sides by 3/-2

I think you mean "Equivalent ratios" if that makes sense, but anyways in order to find Equivalent ratios, you have to either multiply or divide both the numerator and denominator of a given ratio by the same number.
For example: Create a table with the numbers of boys and girls
1. Boys: 3
2. Girls: 5
Next set this as a fraction like this
1. 3/5
Then to find equivalent ratios, multiply both numbers by two and you should get
6/10 (because we multiplied the 3/5 by 2)
Next write 6/10 along the chart of boys and girls
(Write them as fraction like this: 3/5 and 6/10)
Ratio of:
Boys: 3, 6
Girls: 5, 10
and there you have found an equivalent ratio.
