Answer: Try this:
Step-by-step explanation:
798 rounded to one sig. fig. = 800.
8 is already just one sig. fig.
41 rounded to one sig fig. Is 40.
800/8x40
800/320 = 2.5.......
Rounded to one sig fig. =3
Or if you left the entire equation as is and just rounded the answer to 1 sig. fig.
798/(8x41) = 2.4329.......
rounded to one sig fig =2
Without knowing what specifically the question wants estimated to one significant figure, there could be multiple answers.
