Generally, words problem sums
are associated with various objects(usually 2) and the corresponding fractions.
There are many variations to such questions.
The learners needs to spot the word
patterns and understand what the question is asking for.
Model
Method(ANS)
(1) Read the sentence
carefully and spot the word patterns.
(2) Note (a) the Object/Who and (b) the
number/fractions in the sentence.
(3) Determine relationships between Who/Object and
numbers in model form and then
answer the question.
answer the question.
Method:
Step 1: Who/Object? Underline/Circle and
write.
Step 2: Object/actors’ numbers(N)? Draw Model and link
Step 3: Solve
Example:
Ali spent 3/5 of his money and Mary spent 6/7 of
her money. In the end, Ali had ½ as
much money left as Mary. Ali has $50 at first. How much money does Mary have in
the end?
Read the sentence and identify the word pattern/
key information. The keywords are
(1) ‘in
the end’ -> the portion of the money not spent,
(2) Ali has ½ of Mary’s
Step 1: Who/Object? Underline/Circle and write. (Ali, Mary)
Ali
Mary
Step 2: Object/actors’ numbers(N)? Draw Model and link.
Ali
-> 1 – 3/5 = 2/5,
Mary
-> 1 – 6/7 = 1/7
Step 3: Solve
Ali’s money is equal to half of Mary’s
Ali
has $50.
5U
= 50
U = 50/10 = 5
Ali
left 2U -> 2x5 = $10
Mary has 2x10 = $20 in the end
