Answer:
-270
Step-by-step explanation:
The value closest to zero on the number line is greatest because all of the values are negative which is less than zero. -270 is closer to 0 than the other values.
Let x = the unknown number.
Because three-sevenths of the number is 21, therefore
(3/7)x = 21
That is
(3x)/7 = 21
Multiply each side by 7.
3x = 21*7 = 147
Divide each side by 3.
x = 147/3 = 49
Answer: 49
