4x5= 20 which is ur first denominator so then u have to multiply the numerator by 5 which is 5x3=15. so your first reaction is 15/20. then your second fraction you multiply 10x2 for ur denominator so then you multiply to numerator by 2 so that’s 7x2=14 making your fraction 14/20. your final answer should be 15/20>14/20
