Ok so to do this we need to do 90008/(20 20 65*78) = 0.04438 (4 sf)
20 ⋅ 20 ⋅ 65 ⋅ 78 ⋅ f = 90008 2028000 f = 90008 f = 2028000 90008 = 253500 11251
To solve for f in the equation, we found f = 2028000 90008 , resulting in approximately 0.0444. We first multiplied the constants on the left side to simplify the equation. Finally, we divided to isolate f .
