The blog presents the Math Concept, the Math Questions with solutions that teaches in Singapore Primary Schools. You or the kids can learn the skills to deal with the Math Modeling, the Math Problem Solving and the Problem Sum from Lower Primary School to Upper Primary School level after reading the blog postings. This posting is an upper primary school math question on __Fraction__ and Problem Solving.

**Upper primary school mathematics question UPQ584**

In the school anniversary event, Class 6A and Class 6B had to sell 480 dining tickets altogether. After Class 6A sold 3/4 of their share and Class 6B sold 5/8 of their share, each of the class had the same number of tickets left. How many tickets did Class 6B have to sell?

Solution:

Construction the model based on both classes have same number of tickets left finally.

From the model,

20U = 480

1U = 24 tickets

The number of tickets Class 6B need to sell = 8 × 24 = __192__

__Alternative solution:__

The unsold tickets are equal,

1/4 = 3/12 of Class 6A is equal to 3/8 of Class 6B

Total tickets = 480

Total in units = 12 + 8 = 20

20 units = 480

1 unit = 24 tickers

The number of tickets Class 6B need to sell = 8 × 24 = __192__
