Julius put 3 pound on one side side of scale. Abel put 35 1 ounce weight on the other side.

How many more 1 ounce weights does need. To balance the scale?

13 (1 Ounce weights)

Step-by-step 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.
