Get the quotient of each item up to the nearest ten thousandths place. Then, round the decimals to their nearest thousandths. Number 1 is done for you.
1.45 + 8 = 5.6250 5.625
2.77 + 9 =
3.81 7 =
4.93=9 =
5. 88 7=
6.55 + 8 =

9514 1404 393

Step-by-step explanation:

This calculator problem can be handled easily by a spreadsheet, which can round to whatever number of digits you desire.

The point is probably to see if you understand that the thousandths place digit will increase by 1 if the ten-thousandths place digit is 5 or more. (That is the case only for problem 2.)

Additional comment

When doing this with something that only displays 4 decimal digits, you need to be sure that the 4th digit has not been rounded up to 5. For example, ...

  0.00149  rounds to  0.0015  and rounds to  0.001  (not 0.002)

Usually, you would give yourself this assurance by showing the hundred-thousandths place in the calculation if you're intending to round to thousandths.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
