Q&A - P3 Math

12 to 24 means 12 more cards not 1 right?

:?

What BigD meant was that the question asked for function of black cards to be 5/8. If you consider multiples of 8 and 12, the common denominator is 24. Hence, converting 7/12 gives 14/24, while converting 5/8 gives 15/24.

Since the target is 5/8, which is the same as 15/24, you just need to place one more card to make it 15/24.

However, my point is, placing one more card will mean the final fraction is either 7/13 or 8/13. It won't give you 5/8, regardless of the multiples you consider.

Thanks qms,
got it.

I see what you mean, qms.

Actually, the question itself is very cheem, too. It's rather vague and subject to many interpretations. Best if the member who raised this question (Daddy) clarifies.

Draw a shape with 4 sides and 2 smaller angles.


Does it mean the shape drawn should have 4 sides and only 2 smaller angles? oe can it be 4 sides with at least 2 smaller angles (can be more than 2 smaller angles)?

Please help me to understand this question. Thank you.

Please help me to understand this question. Thank you.

My interpretation - 4 sides with exactly 2 smaller angles.

Mrs Chan bought 270 sandwiches for a party. She bought 3 times as many egg sandwiches as ham sandwiches and twice as many ham sandwiches as tuna sandwiches. How many egg sandwiches did she buy ?

Egg sanwiches =6 units.
Ham =2units,
Tuna = 1unit.
therefore 9units = 270
1uint = 270/9 = 30
so egg = 30 x 6 = 180.
