The equation you have written (x:30=7:10) seems to be a proportion. To solve this proportion, we can cross multiply.
To cross multiply, we would first multiply 10 (the denominator of the second fraction) by x (the numerator of the first fraction) and then multiply 30 (the denominator of the first fraction) by 7 (the numerator of the second fraction).
This gives us: 10x = 30*7 10x = 210
To find the value of x, we then divide both sides by 10: x = 21
Therefore, the solution to the proportion x:30=7:10 is x = 21.
