Solution
Sure, let's break it down:
-
First, calculate "18 of 18". The term "of" in mathematics usually means multiplication. So, 18 of 18 is 18 * 18 = 324.
-
Next, calculate "19 of 28". Similarly, this means 19 * 28 = 532.
-
Add the results from step 1 and step 2 together: 324 + 532 = 856.
-
The equation now reads "856 = 5.5 * ?". To find the value of "?", divide 856 by 5.5.
-
So, ? = 856 / 5.5 = 155.64 (rounded to two decimal places).
So, 18 of 18 + 19 of 28 = 5.5 * 155.64.
