The precipitation rate of 550 mm is taken as 100%.
We compose and solve the proportion:
100/124 = 550 / x;
x = 124 * 550/100;
x = 68200/100;
x = 682 (mm) – precipitation fell this year.
Answer: 682 mm.
The product of the middle terms of the proportion is equal to the product of the extreme terms of the proportion.
