Which of the following has a noneterminating decimal expansion? A) 77/210 B) 23/8 C) 17/8 D) 35/50 |
| Answer» {tex}\\frac { 77 } { 210 } = \\frac { 11 } { 30 } = \\frac { 11 } { 2 \\times 3 \\times 5 } \\text { Here, } q = 2 \\times 3 \\times 5{/tex}which is not of the form\xa0{tex}2 ^ { n } 5 ^ { m }{/tex}.So, the rational number\xa0{tex}\\frac { 77 } { 210 }{/tex}has a non-terminating repeating decimal expansion. | |
