Answer:
20 lbs
Step-by-step explanation:
2/5ths of the food would be 20 pounds because:
2/5 * 50 = 20
2/10ths of the food would be 10 pounds because:
2/10 * 50 = 10
If we add those two together, we would get the total amount that the dog ate, which would be 30 pounds. SInce the dog ate 30 pounds of food out of the 50 pounds, there would be 20 pounds left in the bag at the end of two months:
50- ( 20+ 10) = 20
Try this solution:1. If l/m=5/2:5/3, then l/m=3/2 and l=3/2 m;2. If m/n=5/4:7/2, then m/n=5/14 and n=14/5 m;3. l/m/n= 3/2 m: m: 14/5 m; ⇒ l/m/n=3/2:1:14/5 (or l/m/n=15/10/28).
1 in equals 25.4 mm
so in this case you multiply 25.4 times 10
to get 254
