Correct answer is C.
what is 7.69/43.685=?
Answer:
The Correct Answer is 5.6 :)
Step-by-step explanation:
Change the divisor 7.69 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.
We then have the equations:
4368.5 ÷ 769 = 5.6
and therefore:
43.685 ÷ 7.69 = 5.6
Both calculated to 1 decimal places.
