Answer:
Option C is false.
Step-by-step explanation:
A. We are given; 0.7 < 4/5
Now, 4/5 in decimal form is written as 0.8.
Thus,0.7 is less than 0.8. So statement is true.
B) We are given: 2/3 > 0.34
Now, 2/3 in decimal form is written as 0.67.
Thus,0.67 is greater than 0.34, so statement is true.
C) We are given: 2.26 > 214
214 is obviously greater than 2.26. Thus statement is false.
D) We are given: 35/6 > 37/8
Now, 35/6 in decimal form is written as 5.83.
Likewise, 37/8 is written in decimal form as 4.63
Thus,5.83 is greater than 4.63, so statement is true.
Finally, the only false one is Option C
