Answer 1

The answer for A is 5/6 inches.
2 1/3 - 1 1/2 = 2 2/6 - 1 3/6

= 2 + 6 / 6 - 1 3/6 = 8/6 - 1 3/6 = 5/6

The answer for B is 0.0694 feet.

Answer 2

A)

Earlier, The length of the angelfish =
`1 (1)/(2)` inches

Now, the length of angelfish =
`2 (1)/(3)` inches

We have to determine the grown length of angelfish

=
`2 (1)/(3)` -
`1 (1)/(2)`

=
`(7)/(3)- (3)/(2)`

LCM of '2' and '3' is '6',

=
`(14-9)/(6)`

=
`(5)/(6)` inch

Therefore, the angelfish has grown by
`(5)/(6)` inch.

B)

We have to determine the increased length of angelfish in feet.

Since
`1 inch = (1)/(12)` foot

So,
`(5)/(6) inch = (5)/(6) * (1)/(12) = (5)/(72)`

= 0.069 foot.
