Question

9. (i) What is the length whose 30% is 24 cm?​

Answer 1

Answer:

80 cm

Step-by-step explanation:

What is the length whose 30% is 24 cm?​

let the length be x cm

30% of x = 24

$\frac{30}{100} \times x=24 \\\\ 30x=24 \times 100 \\\\ 30x=2400 \\\\ x= \frac{2400}{30} \\\\ x=80 cm$

Length = 80 cm
