If S is the product of the integers from 100 to 200,inclusive,and T is the product of the integers from 100 to 201,inclusive,what is 1/s+1/t in terms if

If S is the product of the integers from 100 to 200,inclusive,一道GMAT数学题.If S is the product of the integers from 100 to 200,inclusive,and T is the product of the integers from 100 to 201,inclusive,what is 1/s+1/t in terms if
t=201s s=t/201
1/s+1/t
=1/(t/201)+1/t
=201/t+1/t
=202/t

如果S代表100到200之间的所有整数,T代表100到201之间的所有整数,那么1/s+1/t用t怎么表示?

I dont no

如果s是100到200中所有整数的乘积(100×101×102×...×200),t是100到201中所有整数的乘积,那么怎么用t来表示1/s+1/t ?
由题意得s=t/201
所以1/s=201/t
所以1/s+1/t=201/t+1/t=202/t
