Take note that 48/8 is merely equal to 6 hence we can say that 3 48/8 is 3+6=9
So we'll have it as:
5 7/8 + 9 = (5+9) 7/8
= 14 7/8

1 2/3 + 3/4
Expressing 1 2/3 as improper fraction you'll have:
1 2/3 = 5/3
5/3 + 3/4 ---------get the LCD in which case is 12
[tex] \frac{5}{3} + \frac{3}{4} = \frac{5(4)+3(3)}{12} [/tex]
[tex] \frac{5}{3} + \frac{3}{4} = \frac{29}{12} [/tex]
expressing it as improper fraction, you'll have
29/12 = 2 5/12
