Evaluate :

`2/3 = 4/6 = 6/9` =   ...   =   ....   = .... = ....

Evaluate : 2/3 times 3/6 + 1/2 times 2/4 - 2/3 times 9/4

Evaluate : 2/3 times 3/6 + 1/2 times 2/4 - 2/3 times 9/4

Evaluate : 2/3 times 3/6 + 1/2 times 2/4 - 2/3 times 9/4

Evaluate : 1/2 times 4/9 + 7/9 times 9/4 + ( -6/7 ) times 9/2

2.3 + 4.4 + 6.9 = "______"

LCM of 2/3, 4/9, 5/6 is:
