If all has 4 legs each, Total legs should b 12 × 4 = 48 So 48 - 34 = 14 extra legs 14÷ 2 = 7pairs of extra legs

Which belongs to 7 birds So there are 7 birds + 5 cats

But answer is 5

I put salah 32. Wait I change

Ok Liao

5 cats

Think we should take the 34 -? Rite

Huh??

Ariel I think i know how to solve alrdy TQ

Goodie. Try the ducks + goats story posted by brenda quah

If all animals were cats then the total legs would be 48 which is greater than 34. To trade 1 cat for 1 bird, you have 2 less legs and you need to have 14 less legs. That means you need to trade 7 cats for 7 birds. So you have 5 cats and 7 birds.

Assume all 12 are cats, there'll be 12×4=48 legs. 48-34=14(extra legs) 14÷2(legs of a bird)=7 birds Hence, 12-7=5 cats. Ans: 5 cats and 7 birds.

U can draw guess and check method table to understand easier:)

5 cats 7 birds

My gal used to do such question in this way. Firstly draw 12 circles to represent the number of animals. Then draw all circles with 2 lines to reprsent 2 legs. With all 12 circles drawn, the no of legs is 24. Then continue to draw another 2 lines till it reaches 34. In the end, there are 5 circles with 4 lines n 8 circles with 2 lines. Answer : 5 cats n 8 birds

Sorry 5 cats 7 birds

Wow v clear explaination Shirley 👍 I will show it to my granddaughter TQ so much 😘😘

U can search you tube for this supposition method. Using supposition method, Step 1 if u r looking for how many cats then starts off with assuming all 12 are birds, which is 12 X 2 legs = 24 legs. Step 2 Difference between actual and assumption. 34 - 24 = 10 Step 3 Diff bw legs 4 - 2 = 2 Step 4 Divide step 2 with step 3 10/2 = 5 U get 5 cats. If u start off with cats as assumption for step 1, ur answer will be 7 birds. (Take note of this). Some schools will teach guess and check first which involves 5-6 columns of working. Toh Hong Choo, pls show Gwyn.

2 methods . My teacher good way for checking during exams.

Can we do it this way? 1 set of cat and bird(2 animals) = 6 legs So 5 sets(10 animals) = 30legs Balance 4 legs comes from 2 birds(to make 12 animals) So, 5 cats and 7 birds

Can! Maybe That'll b how p3s do it since they just learn "grouping"

2 x 12 =24 34-24=10 4-2=2 10÷2=5 (cats) 12-5=7 (birds)

Your welcome

Yes, mdm

Does that means if a pri 5 students will be marked wrong if he uses this method?

O i know alrdy is 30 grandma blurr liso

6 x 5 = 30m If you draw | | | | | | you will see in between 1st to 6th tree is only 5 gap.

30

30: 'FROM' the first tree to the 6th one would have been better wording.

30

30

6-1=5 gaps 5×6m=30m

Draw!

Yup 30

30 It's asked about the distance between 1st to 6th-> 6-1=5 5 x 6 m = 30m

Thank you. Care to share the formula, Gerald Potassium Hydroxide Koh?

First minus off a dollar due to the extra 5 20 cents coins. Then divide by 70cents to get number of 50 cents then add 5 to the answer

Thank you Adrian Ng
