7:( 4/11 m)=56:3.2 solve.
vazorg [7]

Answer:

m= 1.1

Step-by-step explanation:

Given the question as 7:( 4/11 m)=56:3.2 this can be written as;

7: 4/11 m = 56 /3.2

7/4/11m = 560/32 ------------------perform cross multiplication

77*32=560*4/11m

224=2240/11 m

224=203.636 m--------------divide both sides by 203.636 to get m

224/203.636 = 203.636m/203.636

1.1 =m

Testing the value of m in the question

7: (4/11 *1.1) = 56:3.2

7:0.4 = 56 :3.2

70/4 = 560/32

17.5 =17.5
