Mrs. Garcia’s students were asked to find 220% of 75. Each of the students had a different method.
Amy: “I multiplied 2.20 by 75 to find my answer.”
Braden: “I created a table with columns for 100%, 100%, 20%, and 220%. Then I filled in the table and added the values.”
Colton: “I created a table with columns for 100%, 10%, 10%, and 220%. Then I filled in
the table and added the values.”
Danielle: “I divided 75 by 5 to find 20%. Then I added 75 twice to what I found to get my final answer.”
If all of the students completed their steps accurately, which student got the answer wrong?

Answer:

Colton.

Step-by-step explanation:

Amy: 220% is basically [tex]\frac{220}{100}[/tex] which in decimal form, is 2.20.

Braden: 100% + 100% + 20% = 220%, so it is accurate.

Colton: 100%  + 10% + 10% = 120%, not 220%.

Dainielle: 100% of 75 is 75. Dividing the 100% of 75 by 5 makes a 20%. Adding 100% of 75 twice makes 200%. 200% + 20% = 220%, so it is accurate.
