Jawaban:

1. diket= B : 250 gram = 0,25kg

N : 230 gram = 0,23kg

ditanya= T = .....?

%N = .....?

%T = .....?

jawab= T : B - T = 0,25 - 0,23 = 0,02 kg

%N : N/B × 100% = 0,23/0,25×100%=

0,92× 100% = 0,92%

%T : T/B × 100% = 0,02/0,25×100%=

0,08× 100% = 0,08%

2. diket= B : 30kg

T : 1 kg

ditanya= N =......?

%N =......?

%T =.......?

jawab= N : B - T = 30 - 1 = 29 kg

%N : N/B × 100% = 29/30 × 100% =

0,97 × 100%= 0,97%

%T : T/B × 100% = 1/30 × 100% =

0,03 × 100%= 0,03%

3. diket= N : 15kg

T : 0,5kg

ditanya= B = .....?

%N =....?

%T =.....?

jawab= B : N + T = 15 + 0,5 = 15,5kg

%N : N/B × 100% = 15/15,5 × 100% =

0,97×100%= 0,97%

%T : T/B × 100% = 0,5/15,5 × 100% =

0,03×100% = 0,03%
