Jim's dog weighs 18 pounds 10 ounces.

His cat weighs 6 pounds 3 ounces. How

many more ounces does Jim's dog weigh

12.4375 pounds

Step-by-step explanation:

If you break it down

18-6=12

If the number of ounces being subtracted is greater than the number of ounces in the weight that is being subtracted from, decrease the number of pounds by one and increase the number of ounces by 16 in the weight that is being subtracted from.

Subtract the ounces.

Subtract the pounds.

189

Step-by-step explanation:

There are 16 ounces in a pound, so you would multiply 18*16 (288) and add 10 (298) to get the weight of the dog in ounces. Then you would multiply 6*16 (96) and add 3 (99) to find the weight of the cat. You would then subtract the cat's weight (99) from the dog's weight (288) to get the difference (189).
