Explanation:

Problem 1: Emma's Savings

Step1: Identify the goal and percentage

Emma's goal is $300, and she reached 60% of it. To find the amount saved, we calculate 60% of 300.
First, convert 60% to a decimal: \( 60\% = 0.6 \)

Step2: Calculate the amount saved

Multiply the goal by the decimal: \( 300 \times 0.6 = 180 \)

Step1: Find the number of illustrations made

Justin needs to make 80 illustrations and has made 40%. First, find 40% of 80. Convert 40% to a decimal: \( 40\% = 0.4 \)
Calculate the number made: \( 80 \times 0.4 = 32 \)

Step2: Find the number still needed

Subtract the number made from the total: \( 80 - 32 = 48 \)

Step1: Find the number of students who met the goal

There are 28 students, and 75% met the goal. Convert 75% to a decimal: \( 75\% = 0.75 \)
Calculate the number: \( 28 \times 0.75 = 21 \)

Step2: Find the fraction

75% as a fraction is \( \frac{75}{100} = \frac{3}{4} \) (simplified by dividing numerator and denominator by 25).

Answer:

Emma has saved $180.
