After :
Ms Tan: ========== 5 units
Ms Lee: == 1 units
Total = 6 units
Total = 180 strawberries
1unit = 180/6 = 30 strawberries
Before :
Ms Tan = 5 units + 13 = 150 +13 =163 strawberries
Ms Lee=1 unit  13 = 30  13 = 17 strawberries

Hi,
But I still wonder why do we have to divide first instead of minus the 13 first?

Mrs Tan and Mrs.Lee had 180 strawberries altogether.
After Mrs.Tan gave 13 strawberries to Mrs.Lee, [Action: Minus 13 (1st]
she had 5 times as many strawberries as Mrs.Lee [Result: Total of 6 Times (2nd)].
How many strawberries did Mrs. Tan have at first?
As you are working backwards, so you act on 2nd (First) {6 Times)  So now Divide by 6.
Then act on 1st (Second) (Miuse 13)  So now add 13[/u[/b]].
