Naomi had a total of 155 apps on her phone. She recognized that 20% of the apps were games. How many game apps did Naomi have on her phone?

15
30
31
55

To find 20% of 155, you multiply 155 by 0.20.

155 * 0.20 = 31.

Therefore, Naomi had 31 game apps on her phone. The correct answer is 31.

To find the number of game apps Naomi had on her phone, we need to calculate 20% of the total number of apps she had.

Step 1: Convert the percentage to a decimal. Divide 20 by 100: 20/100 = 0.20.

Step 2: Multiply the decimal by the total number of apps. 0.20 x 155 = 31.

Therefore, Naomi had 31 game apps on her phone.

Answer: 31.
