Question

the product of three number is 5 1/2. if two of them are 2 2/7and 1 3/8,find the third​

Answer 1

Answer:

103/56 is the correct answer

Step-by-step explanation:

Let it be x

$x + 1\frac{3}{8} + 2 \frac{2}{7} = 5 \frac{1}{2} \\ x + \frac{11}{8} + \frac{16}{7} = \frac{11}{2} \\ x + \frac{77 +128 }{56} = \frac{11}{2} \\ x + \frac{205}{56} = \frac{11}{2} \\ x = \frac{11}{2} - \frac{205}{56} \\ x = \frac{308 - 205}{56} \\ x = \frac{103}{56} ans.$
