Simplifying Ratios
1. 15 dogs : 45 dogs = 15 : 45 = 15 / 45 = 1 / 3(fraction form) = 1 : 3(ratio form)
2. 12 guitars : 75 instrument band = 12 : 75 = 12 / 75 = 4 / 25 = 4 : 25
3. 25 old stamps : 100 postage stamps = 25 : 100 = 25 / 100 = 1 / 4 = 1 : 4
4. 15 mangoes : 25 mango cakes = 15 : 25 = 15 / 25 = 3 / 5 = 3 : 5
5. 35 correct answers : 50 item test = 35 : 50 = 35 / 50 = 7 / 10 = 7 : 10
