A skirt that is 
cm long has a hem of 
cm. How long will the skirt be if the hem is let down?
Solution:-
From the question it is given that,
Length of the skirt =
cm = 287/8 cm

Manavi and Kuber each receives an equal allowance. The table shows the fraction of their allowance each deposits into his/her saving account and the fraction each spends at the mall. If allowance of each is ₹ 1260 find the amount left with each.
Solution:-
| Where money goes | Fraction of allowance | |
| Manavi | Kuber | |
| Saving Account | ½ | 1/3 |
| Spend at mall | ¼ | 3/5 |
| Left over | ? | ? |
Solution:-
From the question,
Manavi and Kuber each receives and equal allowance = ₹ 1260
Let us assume total cost be ₹ 1
For Manavi, left over = Total cost – Total spends
= 1 – (½ + ¼)
= 1 – (2 + 1)/4
= 1 – (3/4)
= (4 – 3)/4
= ¼
So, Amount = 1260 × ¼ = ₹ 315
For Kuber, left over = Total cost – Total spends
= 1 – (1/3 + 3/5)
= 1 – (5 + 9)/15
= 1 – (14/15)
= (15 – 14)/15
= 1/15
So, Amount = 1260 × (1/15) = ₹ 84
