Answer 2

@harz360 !

Answer 3

sorry lb oz

Answer 4

I suppose you mean 16 oz in 1 lb.
So 4 lb 6oz equals 4*16+6=70 oz.
Do the same for the others, add all three together, and divide by 3 to get the average.
Convert back to lbs and oz, and that's your answer.

Answer 5

i still dont understand

Answer 6

Example:
Three cakes weight 2 lb 8oz, 1 lb 3oz, 2 lb 5 oz.
Step 1:
Convert all to the smaller unit, oz.
2 lb 8oz = 2*16+8=40 oz
1 lb 3oz = 1*16+3 = 19 oz
2 lb 5 oz = 2*16+5 = 37 oz

2. Calculate sum (in smaller unit)
sum = 40+19+37 = 96 oz

3. Calculate average
average = sum/number of cakes = 96 oz / 3 cakes = 32 oz/cake

4. Convert to appropriate units
1 lb=16 oz
so 32 oz = 32/16 = 2 lb 0oz

5. Give answer in words
The average weight of each cake is 2 lb 0 oz each.
