3/5 = 12/20
2/4 = 10/20
Since 12 is greater than 10, Vinny ate more
2 hours = (4) 30 mintues
<span>so, (1) 30 minutes: (4) 30 minutes </span>
<span>so, 1:4</span>
Answer:
15
Step-by-step explanation:
12 X 15 is 180, which is closest to 187, we have to add a 5 in the space next to 71 and 180 under 187
