I am doing some college algebra homework and I am on the unit that is called using equations to solve word problems. The problem is a number one fourth of that number, and 1/5 of that number or add it. The result is 87 what is the original number

Assume the number is y

so 1/4y +1/5y = 87

9/20y = 87

y = 193.33

where did 9/20 come from?

adding 1/4 and 1/5 = 9/20

Correction Please

y +1/4y +1/5y = 87

1 9/20y = 87

y = 60
