Rewrite as a square or a cube: 3 3/8 = 1 11/25=

1)

3 3/8=  (3/1) + (3/8)=
     = (3x8)/8 + (3/8)
     =(3x8 +3) / 8              putting both numbers with the same denominator
      =27/8
27 is the same as 3³      3x3x3= 27
8 is the same as 2³        2x2x2= 8
= 3³÷ 2³

2)
1 11/25= (1/1) + (11/25)
= (25/25) + (11/25)     putting both numbers with the same denominator
= (25+11)/25
=36/25
36 is the same as 6²     6x6=36
25 is the same as 5²     5x5=25

6²/5²

They are somewhat similar
