Calculations and approximations
How should numbers be expressed in 5.0. EG: in the ballast4.0 example 11.1  71.8 psf is approximated to 72, the final result changes from 17,232 lbs to 17,280. Also, should that be typed has 17280 in the test? Thanks

Valentina,
I assume you are talking about QFIB items? Scoring in QFIB items is able to account for various rounding techniques when determining the correct answer  whether that is throughout the calculation or at the very end. If specfic rounding is required then the item will say so. You are also responsible for understanding when rounding is appropriate, such as you can't have 3.2 toilets or parking spaces. And yes, you would just type "17280" in the answer box.
Hope this helps.

Computer scoring actually makes a variable number of decimals easier to score! If rounding to a specific number is required, then the item will say so. Otherwise, the computer will accurately score either one. Don't overthink this too much  focusing on studying the content that matters.
