Answer: the answer is choice b
Step-by-step explanation:
Answer:
B. <
2.7 * 10^3 is < 27 * 10^3
since
27 * 10^3 = 27000
2.7 * 10^3 = 2700
2700 < 27000
now since multiplying by 10 moves the decimal to the right, just looking and mentally comparing them. since they are both multiplied by 10^3 you're left with 2.7 and 27
27 is greater than 2.7
so
your answer is B or <
