Let the m:f in mathematics class be 4x:5x and that in English class be 5y:4y
Given that \(\frac{5y-4x}{4x}=0.5.....5y-4x=2x.....5y=6x....y=6x/5\)
Ratio of f in mathematics to English is 5x:4y or 5x:4*6x/5=25x:24x=25:24

Hope it helps

Mathematics class Male/Female = 4/5
English class male/female = 5/4 The recipient said that there are 50% more boys in English class than boys in mathematics class, which is also 3/2 times, or 1.5 times
Adjust the number of boys in English classes to 3/2 times the proportion of boys in mathematics classes
3/2 times 4 is 6 math class male/female = 4/5
English class Male/Female = 5*6/5 /. 4*6/5 =. 6/ (24/5) Now take math girls as 5/24/5 compared to English girls =. 25/24
