Assuming the question is as follows: by hitting ? instead of /
2/45 + 3/20/(2/25)
solve 3/20(2/25) = 3/20 x 25/2 = 75/40 =15/8
therefore 2/45 + 3/20 / (2/25) = 2/45 + 15/8
= 2/45 + 15/8 = 16+675/360
= 691/360
= 1.919444444
1.91944444444444 is rational number (the decimal number is recurring at the end as 4 and can be easily converted to a fraction)
