Let, the number be 7x and 11 x.
7x+7/11x +7=2/3
=> By cross multiplication We get.
=>21x+21=22x+14
=>21x-22x=14-21
=>-x= -7
=>x=7
Hence, the numbers are
7x=7×7=49 and 11x=11×7=77
7x+7/11x +7=2/3
=> By cross multiplication We get.
=>21x+21=22x+14
=>21x-22x=14-21
=>-x= -7
=>x=7
Hence, the numbers are
7x=7×7=49 and 11x=11×7=77
