Question

a length of 1m 71cm in the ratio of 11:8

Answer 1

99cm : 72 cm is the ratio of 1m 71cm in ratio of 11:8

Answer 2

Total length = 1 m 71 cm
                   =  171 cm
Let the ratios be 11x and 8x
According to question,
11x + 8x  =   171
     19x     =   171
        x      =   171 / 19
       x       =   9 cm

Hence, = 11 : 8 
            =  11x : 8x
            =  11* 9  :  8 * 9
            =   99  :  72
            =  99 cm  :  72 cm
