71/2 ×11/4 : 5×11/4 :: 5×11/4 : 5×3
142/8 : 55/4 : 15 =a:b:c
or 17.75:13.75:15
No, above ques is exactly find a:b:c when a:b=7 whole 1/2 :5 b:c=1 whole 1/4 :3
7 1/2 =15/2 1 /4 =5/4
*1 1/4=5/4
So we have a:b = 15/2:5 and b:c =5/4 :3
or 7.5:5 and 1.25:3
so 7.5×1.25:5×1.25 and 5×1.25:5×3
9.375:6 25:15 =a:b:c
