May sold 15 packets of salt and some packets of sugar.1 over 6 of the packets sold were salt.How many packets of sugar were sold?


Can someone solve this?

[PapayaDad]

1/6 = salt so 5/6 = sugar


since 1/6 = 15

5/6 = 15 x 5 = 75

Hi

Please confirm if highlighted word 'now\" should be read as more.

Is underlined word \"more\" in the question?

Hi fohope


Basing on the original question, you still can get an answer, but it'll not be in nice whole numbers.

(3P+4) + ((3P+4) + 3P ---- 43

The answers will be in decimals.

Best wishes

Hi Tianzhu,

The teacher printed the wrong number in the question. It should be 44 instead of 43.

Thanks.

Hi

Then, the answer will be in whole numbers.

(3P+4) + ((3P+4) + 3P ---- 44

9P ------ 36

P ------ 4

Cost per pen ----- 4

Cost per book ------ 16

I think the question should be 48 more girls. If so the ans is 112 pupils. Is the answer correct?

5u = girls
2u = boys
5u-2u = 48
1u = 48/3 = 16
16*7 = 112

That is correct. Should be \"48 more\" girls.

Same working I had. However, I am having difficulty understanding the question. Why do they add \"more\" instead of asking \"What is the total number of students seated in the auditorium?\".
