Final answer:
To calculate the quotient of 0.728 divided by 8, perform long division to obtain 0.091. This corresponds to option A, which is the correct choice to four significant figures.
Step-by-step explanation:
To find the quotient of 0.728 divided by 8, you need to perform the division. Place the decimal point directly above its position in the dividend when setting up the division. Calculate as follows:
8 into 7 goes 0 times, so write 0 to the left of the decimal point in the quotient.
Bring down the next digit (2), and ask how many times 8 goes into 72, which is 9 times.
Multiply 8 by 9 to get 72 and subtract this from 72 to get 0.
Bring down the final digit (8), and ask how many times 8 goes into 0, which is 0 times.
Write this final zero in the quotient to get 0.090.
Given the options, the correct quotient to four significant figures is 0.091, which corresponds to option A.
