Answer:
There are 30 temporary employees
Step-by-step explanation:
<em>To find </em><em>x% of quantity A</em><em>, multiply x% by A after change x% to the normal number by divide it by 100 ⇒ </em><em>(x ÷ 100) × A</em>
Let us use this rule to solve the question
∵ The local water slides have 100 employees
∵ 30% of them are temporary
∴ The number of temporary employees = 30% × 100
∵ 30% = 30 ÷ 100 = 0.30
∴ The number of temporary employees = 0.30 × 100
∴ The number of temporary employees = 30
∴ There are 30 temporary employees
