In a bag of red and green sweets, the ratio of red sweets to green sweets is 3:4. If the bag contains 120 green sweets, how many red sweets are there?

Red to green sweets:

3:4

Let the red sweets= x.

x:120

120/4= 30

3*30= 90

90:120

If a bag contained 120 green sweets, then it contained 90 red sweets.

I hope this helps!
