Hello My Friend!
Result:
[tex]2[/tex] [tex]1/2 - 7/8 = 13/8 = 1 5/8 = 1.625[/tex].
1. Conversion: 2 1/2 = 2 · 2 + 1 = 5
------------ ----
2 2
2. Subtract: 5/2 - 7/8 = 5 x 4 - 7 = 20 - 7 = 20 - 7 = 13
-------- --- --- --- -------- ----
2 x 4 8 8 8 8 8
The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 8) = 8
Therefore, The Correct Answer = 1 5/8 or 1.625. <===============
