Solve using a proportion.

2ft

For every foot it needs to be 12 ft. So 1 3/4 is 1 foot and 9 inches. Cause we have the whole number which is 1 and 3/4. 3/4 isn’t a whole number it’s a fraction of 12. 1/4 if 12 is 3 cause 12 split into 4 parts is 3. Now we have 3/4 which is 3 of the 1/4ths. We said 1/4 is 3 and if we have three then we multiply 3 x 3 and get 9.

So

1 ft 9 in

But it says to round to the nearest integer so 1 turns to 2.

Hope this helps
