there are 6 terms in the simplified expression
1 meter is 100 centimeters so do 200÷10 what does that leavr you with ? 20
The second one on the top right
3 decimal places would be where the 9 is, since the next number is 8 , the 9 would become a 0 and the number before it (5) would become a 6
so it would be 977.260
2 weeks (14 days) X 23.93 hours a day = 335.02 hours in 2 weeks
so 14 x 23.93 = 335.02
hope I helped:)
