Answer:
2 : 5
Explanation:
Divide each part of the ratio by 9
378 : 945 = 42 : 105 ← divide each part by 7
42 : 105 = 6 : 15 ← divide each part by 3
6 : 15 = 2 : 5 ← in simplest form
2:5
We can simplify the ratio 378 : 945 by dividing both terms by the greatest common factor (GCF).
The GCF of 378 and 945 is 189.
Divide both terms by 189.
378 ÷ 189 = 2
945 ÷ 189 = 5
Therefore:
378 : 945 = 2 : 5
