12. Wendy sliced a loaf of bread into 12
equal slices. She used 4 of the slices to
make sandwiches. What fraction of the
loaf of bread was left?

2/3 the

loaf of bread was left.

Step-by-step explanation:

Wendy sliced a loaf of bread into 12

equal slices. This means that the portion or size of each slice is 1/12.

She used 4 of the slices to

make sandwiches. This means that the portion of the loaf of bread that she used to make the sandwiches is

4 × 1/12 = 4/12 = 1/3

Therefore, the fraction of the

loaf of bread that was left is

1 - 1/3 = 2/3

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
