You can solve this problem two ways.

1. Divide 68g by 100 to get how many grams per pound and multiply that by 150. This is the hard way.

2. Multiply 68 by 1.5 to get your answer. This is possible because 150 is 1.5 of 100, so multiplying the amount for 100 by 1.5 gives you your answer.

Ruiz needs to buy a countertop for a kitchen. He calculated the area to be 16 square feet. The actual area is 15.4 square feet.

igomit [66]

Percentage error $=\frac{error}{actual measurement} \times 100$
Here error = 16 - 15.4 = 0.6
Therefore, percentage error $=\frac{0.6}{15.4} \times 100=0.039 \times 100$
=3.9%
