Use ( < , > , =) to compare 2/3 and 3/4 a) none of the above b) 2/3> 3/4 c) 2/3 < 3/4 d) 2/3 = 3/4

Option C: 2/3 < 3/4

Step-by-step explanation:

Method 1:  (By calculating decimal value)

2/3 = 0.667 (approx)

3/4 = 0.75

Now comparing both values:

0.75 > 0.667 or we can say 2/3 < 3/4

Method 2: (By making denominator same)

For denominators 3 and 4 the LCM would be 12 so,

Multiply 2/3 with 4/4 to make denominator= 12:  

2*4 / 4*4 = 8/12

Multiply 3/4 with 3/3 to make denominator= 12:

3*3 / 4*3 =9/12

Now we can decide by comparing numerators (as denominators are same) :

8/12 < 9/12

so  2/3 < 3/4  (hence proved)

(-1,-0.5)

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.
