If Jane takes 6 weeks to built the house on her own, then in 1 week she builds 1/6 of the house.
So in 4 weeks, she builds :
4/6 = 2/3 of the house
Since they built 1 house together in 4 weeks,
1 - 2/3 = 1/3
Karen built the other 1/3 of the house in the 4 weeks.
5b)
2/3 - 1/3 = 1/3
Jane built 1/3 more than Karen in the 4 weeks.
5a)
If Karen built 1/3 of the house in 4 weeks, then for the whole house,
4 x 3 = 12
She would take 12 weeks to build the house herself
So in 4 weeks, she builds :
4/6 = 2/3 of the house
Since they built 1 house together in 4 weeks,
1 - 2/3 = 1/3
Karen built the other 1/3 of the house in the 4 weeks.
5b)
2/3 - 1/3 = 1/3
Jane built 1/3 more than Karen in the 4 weeks.
