Question

ruben is buying bricks for a project. he knows that 5 bricks weigh 26 1/4. he wants to know the weight of 24 bricks

Answer 1

the weight of 24 bricks is :

`124(4)/(5)`

Explanation:

`26(1)/(4) =26+(1)/(4) =(26* 4)/(4) +(1)/(4) =(105)/(4)`

It is clear that there is a proportional relationship between the number of bricks and their weights then :

`(26(1)/(4) )/(5) =(x)/(24) \Longrightarrow (\left( (105)/(4) \right) )/(5) =(x)/(24) \Longrightarrow (26)/(5) =(x)/(24)`

`\Longrightarrow x=(26* 24)/(5) =(624)/(5) =124(4)/(5)`
