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

Answer:

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
