the lenth of a poal is 11\2 meter. 1\3rd of the poal is painted red, 1\4th is painted in green and the remaining portion in blue. find thd lenth of the portion painted in blue?

Answer 1

It would help if you proofread your questions before you posted them.

Is the length of the pole 11.2 meters or 11 halves (11/2) of a meter?

1 - 1/3 - 1/4 = 1 - 4/12 - 3/12 = 5/12

So the blue portion is 5/12 of whatever the length of the pole is.

Answer 2

11/2-{(11/2X1/3)+(11/2X1/4)}=2 7/24

Answer 3

11/2-{(11/2X1/3)+(11/2X1/4)}
=11/2-(11/6+11/8)
=11/2-77/24
=55/24=2*7/24
