Final answer:
48% of Mrs. Ruiz's students do not bring their homework daily, which corresponds to the decimal 0.48 and the simplified fraction 12/25.
Step-by-step explanation:
The question asks for the decimal and fraction that represents the percent of students in Mrs. Ruiz's class who do not bring their homework to school daily. If 52% of the students do bring their homework, then 100% - 52% = 48% do not. To convert this percent to a decimal, we divide by 100. Thus, 48% is equivalent to 0.48 as a decimal. To express this as a fraction, we have 48/100, which can be simplified to 12/25 when reduced to lowest terms.
