Question

you need to compare students and adults in relation to laptops. because students and adults are grouped by rows, find the row relative frequencies. write the ratios of each value to the total in that row. then write the ratio as a decimal. round to the nearest hundredth.
tablet laptop total
students 57; \\(\frac{57}{78}\\) ≈ \\(\square\\) 21; \\(\frac{21}{78}\\) ≈ \\(\square\\) 78; 1.00
adults 13; \\(\frac{13}{22}\\) ≈ \\(\square\\) 9; \\(\frac{9}{22}\\) ≈ \\(\square\\) 22; 1.00

Explanation:

Step1: Calculate student tablet ratio

$\frac{57}{78} \approx 0.73$

Step2: Calculate student laptop ratio

$\frac{21}{78} \approx 0.27$

Step3: Calculate adult tablet ratio

$\frac{13}{22} \approx 0.59$

Step4: Calculate adult laptop ratio

$\frac{9}{22} \approx 0.41$

Answer:

Students (Tablet): $0.73$
Students (Laptop): $0.27$
Adults (Tablet): $0.59$
Adults (Laptop): $0.41$
