Answer 1

28 4/7 % ≈ 29%

Explanation:

4 kg - weight of sugar

10 kg - mass of water

4kg + 10kg = 14kg - weight of the syrup

`(4kg)/(14kg)=(2)/(7)`

The sugar is 2/7 of the weight of the syrup.

Convert to the percentage:

`(2)/(7)=(2)/(7)\cdot100\%=(200)/(7)\%=28(4)/(7)\%\aaprox29\%`

10 kg - mass of water

4kg + 10kg = 14kg - weight of the syrup

The sugar is 2/7 of the weight of the syrup.
