P5/P6 Math: 3 Item Types with Different Quantities and Values

Such questions uses fraction and multiples(ratio) to give a breakdown of the distribution of 3 different items. Each of the item have different values and the total value of all quantities of 3 items is also provided.

Such questions are common in Paper 2 of P5 exams.
Calculator usage is allowed.

Erica bought a number of durians,watermelons and jackfruits 
from the market and spent $620 altogether.

P5 Math: Percentage and Ratio to describe 3 Values

Once students are taught percentage and ratio, these 2 concepts can be presented in the same problem sum such as the one below.

Students must make use of the "repeated identity" method to solve.

Such questions are common in WA2 and SA2 of P5 exams.
Calculator usage is allowed.

There are oranges, pears and apples for sale at a fruit stall.
15% of the fruits at the stall are oranges.
The ratio of pears to apples at the stall is 12:5.
There are 150 more apples than oranges at the stall.

How many fruits are there altogether at the fruit stall?

P5 Math: Splitting 2 Groups to become 4

A group of items is being split into 2 using fractions.
Each of the group is being sub-divided again using another pair of fractions.

Such questions require the student to recognise the repeated identity in order to ensure that the fractional split in each group is correctly processed.

These questions often appear in Paper 2 of P5 and P6 exams.
Calculator usage is allowed. 

A similar version of this question using percentages can also be found here.


At first, 1/3 of the fruits in the basket are red grapes, the rest are green grapes.
1/2 of the red grapes and 1/4 of the green grapes are sold.
150 red and green grapes were sold altogether.

How many grapes were there at the basket at the start?

P6 Math: Splitting 2 groups to become 4

For questions like these, there will be a ratio to split a larger group into 2.

Each of the smaller group is divided into 2 smaller groups.
Students are required to make use of repeated identity concept in order to solve such questions.

These questions often appear in Paper 2.
Calculator usage is accepted.

The children in a dance hall are divided equally into 2 groups.
In the first group, there were 20 more girls than boys.
In the second group, there were 12 more boys than girls.

P5/P6 Math: Repeated Identity (Ratios as Fractions)

The question presents 3 unique items of different quantities and each or 2 of them are compared with the total using "fractions".
2 of such comparison statements are given and the total is also known.

Questions like these requires students to use "ratio" methods to solve a seemingly "fraction" problem sum.
Cocepts such as "total unchanged" and "repeated identity" are required to solve such questions.

These questions will usually appear in Paper 2 of P5 and P6 exam papers.
Calculator usage is allowed.

Patricia has a collection of 135 books, stickers and pens.
2/3 of these items were not pens.
3/5 of these items were either books or pens.

a) How many items of Patricia's collection were stickers?
b) What is the ratio of her stickers to pens?

P5/P6 Math: Fractions and Ratio vs Repeated Identity

This following fraction/ratio question requires students to be able to identify the repeated identities in order to be able to make sense of the relationship between each ratio/fraction.

A starting ratio is given between 2 items.
Each of the item is then split again into 2 types via fractions.
The relationship between 2 of the split items are given with a comparison statement.
[eg more than, less than ]

Such questions usually appear in Paper 2 of P5 SA2 and P6 exams.

Calculator usage is allowed.
