Answer:
13 (1 Ounce weights)
Explanation:
Unit of conversion: 1 Pound =16 ounce
3 Pounds = 3 x 16 =48 Ounce
Therefore:
- Julius put 48 Ounce on one side side of scale.
- Abel put 35 1 ounce weight on the other side .
Let the number of 1 Ounce weight needed by Abel =x
Then, to balance the scale, the expression below holds.
48=35+x
Subtract 35 from both sides
48-35=35-35+x
x=13
Abel needs 13 more 1 Ounce weights to balance the scale.
