Accepted Answer

Step 1: Calculate total sales for manufacturer Q from 2016 to 2020.
Q sales = 280 + 290 + 310 + 310 + 330 = 1520

Step 2: Calculate total sales for manufacturer S from 2016 to 2020.
S sales = 400 + 420 + 430 + 440 + 450 = 2140

Step 3: Find the ratio Q : S = 1520 : 2140

Step 4: Simplify the ratio by dividing both numbers by their GCD.
GCD of 1520 and 2140 is 20.

1520 ÷ 20 = 76
2140 ÷ 20 = 107

Therefore, the ratio is 76 : 107.
