Barlow School has the greater number of boys by #178#.

As at Barlow School, #4/9# of the #873# students are boys,

number of boys are #4/9xx873=4/(cancel9^1)xxcancel873^97#

= #4xx97=388#

At Willow School, we have #2/3# of the #630# students, girls.

Hence, number of girls are #2/3xx630=2/(cancel3^1)xxcancel630^210#

= #420#

Hence, number of boys are #630-420=210#.

Hence, Barlow School has the greater number of boys by

#388-210=178#.
