Hey there!
⇒ Percentages runs out of 100
⇒ The word "of" means multiply in mathematical terms
New equation: 40/100 × 30/1
40/100 × 30/1
40/100= 40 ÷ 20 / 100 ÷ 20 = 2/5
New equation: 2/5 × 30/1
2(30) / 5(1)
2(30) = 60
5(1) = 5
60 / 5 = 60 ÷ 5 / 5 ÷ 5 = 12
∴ Answer: 12 ✅
Good luck on your assignment and enjoy your day!
