Answer :
The answer is 9/4.if you multiply 3/8 by 6 you look for the number that can divide the both of them without remainder.
so if 6 feet is 3/8 of her total ribbon, then each 1/8 should consist of 2 feet of ribbon. they wanna know what she had at 1st so 3/8+3/8= 6/8 of ribbon also ='s 12 feet of ribbon. next we know 1/8 is 2 feet so 2/8= 4 feet, 12+4= 16 feet of ribbon.
