Mrs. Garcia’s students were asked to find 220% of 75. Each of the students had a different method.

ludmilkaskok [199]

Answer:

Colton.

Step-by-step explanation:

Amy: 220% is basically $\frac{220}{100}$ 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.
