Answer:
Step-by-step explanation:
note :
a/b = c/d means : ad = bc
comparing : 15×18 and 14×20
15×18=270 and 14×20 = 280
conclusion : 15/20=14/18 is false
15/20 can be simplified down to 3/4
14/18 can be simplified down to 7/6
Comparing the two simplified forms, they do NOT equal each other, so the proportion would be false
