Answer:
A. 18/16 + 22/24 = 49/24
B. 23/13 + 42/15 = 297/65
C. 27/16 + 15/12 = 47/16
Step-by-step explanation:
18/16 + 22/24
= 54/48 + 44/48
= 98/48
= 49/24
…………………
23/13 + 42/15
=(23×15)/(13×15) + (42×13)/(13×15)
= 345/195 + 546/195
= 891/195 (divide both sides by 3)
= 297/65
……………………………………
27/16 + 15/12
= 81/48 + 60/48
= 141/48 (divide both sides by 3)
= 47/16
