Question

Fill in the blanks in rational number 2 upon 7 = 8 upon dash = dash upon -63

Answer 1

Let first dash be x and second be y

=> 2/7 = 8/x = y/(-63)

cross multiplying first equation

=> 2*x = 7*8

=> x= 56/2 = 28

now cross multiplying the second equation

=> x*y= -63*8

=> 28*y= -63*8

=> y= -63*8/28

=> y= -18
