hey hey im gonna need some help on solving proportions on maps will ya help me please!

ok so 1 inch=30 yards so 4 inch=?
1/30=4/x
1x=30(4)
x=120
so the actual distance is 120 yards
Answer:
120 yards
Step-by-step explanation:
We know that 1 inch = 30 yards
1 inch = 30 yards
But we want to work out how much yards in 4 inches so
1 inch = 30 yards
(Multiply by 4 to from 1 to 4 so we must multiply 30 by 4)
4 inch = ? yards
4 inch = 120 yards
Hope this helps :)
Have a great day !
