Ta có : \(\frac{74}{111}=\frac{a}{87}\Leftrightarrow74.87=111.a\Rightarrow a=\frac{74\cdot87}{111}=\frac{6438}{111}=58\)

Vậy a = 58

conan mà như bạn chắc chết

Ta có:\(\frac{74}{111}=\frac{74:37}{111:37}=\frac{2}{3}=\frac{2x28}{3x28}=\frac{58}{87}\)

Vậy a=58

87 X 74:111 la ra

Ta có:\(\frac{74}{111}=\frac{a}{87}\)

            74.87=a.111

             6438=a.111

              a=6438:111

              a=58

Vậy a=58

\(\frac{74}{111}=\frac{a}{87}\Rightarrow a=\frac{74\times87}{111}=58\)

Vậy a là 58.

A bằng 58

\(\frac{74}{111}=\frac{a}{87}\Leftrightarrow74.87=111.a\Rightarrow a=\frac{74.87}{111}=\frac{6438}{111}=58\)

Vậy a = 58

74/111=a/87=>a=74x87:111=58

74 : 111 = \(\frac{a}{87}\)

74 : 111 x87 =a

a=6438 : 111 

a=58

 vậy a = 58

74 / 111 = a / 87

Vậy a = 58

Ta có:\(\frac{74}{111}=\frac{2}{3}=\frac{2.29}{3.29}=\frac{58}{87}\)

Vậy a=58

bằng 58/87

A=74(111/87)=58/87

= \(\frac{58}{87}\)

a=74/(111/87)=58

a = 87x74:111=58
