Answer:
267/40
Step-by-step explanation:
Simplify the following:
5 + 3/8 + (1 + 3/10)
Put 1 + 3/10 over the common denominator 10. 1 + 3/10 = 10/10 + 3/10:
5 + 3/8 + 10/10 + 3/10
10/10 + 3/10 = (10 + 3)/10:
5 + 3/8 + (10 + 3)/10
10 + 3 = 13:
5 + 3/8 + 13/10
Put 5 + 3/8 + 13/10 over the common denominator 40. 5 + 3/8 + 13/10 = (40×5)/40 + (5×3)/40 + (4×13)/40:
(40×5)/40 + (5×3)/40 + (4×13)/40
40×5 = 200:
200/40 + (5×3)/40 + (4×13)/40
5×3 = 15:
200/40 + 15/40 + (4×13)/40
4×13 = 52:
200/40 + 15/40 + 52/40
200/40 + 15/40 + 52/40 = (200 + 15 + 52)/40:
(200 + 15 + 52)/40
