remaining?
A.4/12
B.1/3
C. 30%
D.0.3

Answer 1

The number which doesn't represent the amount of pizza left is 30%

Using the parameters from the model ;

• Number of bars = 3
• Number of bars with pizza = 1

Amount of pizza left as a fraction ;

• Number of bars with pizza / Number of bars

Now we have :

In fraction = 1/3

multiplying by 4 ;

• 1/3 × 4/4 = 4/12

Expressing as a percentage ;

1/3 × 100% = 33.33%

Expressing as a decimal ;

• 1/3 = 0.333

Hence, the number which doesn't represent the amount of pizza left is 30% .
