Question

Someone do this please, ty.

Answer 1

`\boxed{\rm x = 5}`

Explanation:

`\rm \cfrac{12}{20} = \cfrac{3}{x}`

Find the missing value.

Solution with work shown:

Use criss-cross multiplication:

• 
  `12 * x = 3 * 20`
• 
  `12x = 60`

Divide both sides by 12:

• 
  `\cfrac{12x}{12} = \cfrac{60}{12}`

• 
  `x = 5`

Hence,the missing value is 5.

Answer 2

5 is the missing value.

Explanation:

12x = 60

x = 60/12

x = 5
