Answer:
879/110
989
Step-by-step explanation:
simplified expression of (3.23 +4.75)
bar on 3 and bar on 75
x = 3.2333333
10x = 32.33333333
100x = 323.333333
100x - 10x = 323.3333333 - 32.333333
=> 90x = 323 - 32
=>x = 291/90
y = 4.75757575
100y = 475.757575
100y - y = 475.757575 - 4.75757575
=> 99y = 471
=> y = 471/99
291/90 + 471/99
= (291 * 11 + 471*10)/990
= (3201 + 4710)/990
= 7911/990
= 879/110
879 + 110 = 989
