Step-by-step explanation:

It is given in the question that ;

Weight of 32 magazines=3kg

Answer 2

Answer:

∴ The weight of $80$ magazines is $7.5$ kg.    

Step-by-step explanation:

• In context with question asked,
• We have to find the weight of $80$ magazines.
• It is given that, the weight of $32$ magazines = $3$ kg
• To find the weight of $80$ magazines, first we have to find the weight of one magazine.
• Then, by multiplying the weight of one magazine with number of $80$magazines, we can find the weight of $80$ magazines.
• Now,

       Weight of one magazine = $\frac{3}{32}$

                                           = $0.09375$ kg

• So,

     Weight of $80$ magazines = Weight of one magazine $\times$ Number of magazines

                                       = $0.09375$ $\times$ $80$

                                       = $7.5$ kg

• ∴ The weight of $80$ magazines is $7.5$ kg.
