You can solve this one by asking what is 28 divided by 4? 28/4 = 7. So 7 x 3 = 21. So 3/4th of 28 is 21.

3/4 + 1/7 = 3/4 x 7/7 + 1/7 x 4/4 = 21/28 + 4/28 = 25 /28
1 (a whole).
3 of anything plus 3 more of the same thing is 6 of them.
1 and (3/4) = 1.751.75 + 1.75 = 3.5 (or three and a half)
345
1 and 3/4ths of an inch by 1 and 3/4ths of an inch
Trick question. 18 and 3 4ths is 18 3/4 which is already simplified!
