3u = 45 1u = 15 7u = 105 B) 15u = 225 225+ 25 = 250 250: 75 = 3:1

You can try the following method. Let Elyssa's money be 4 units. Lizbeth ---> 7 units June ---> 4 units - $6 Total units ---> 7 units + 4 units + 4 units - $6 = 15 units - $6 If each of them have the same amount in the end, they will each have (15 units - $6) / 3 = 5 units - $2 Before: Elyssa has 4 units After she receives $16 from Lizbeth, Elyssa has 5 units - $2. So, 5 units - $2 - 4 units = $16 1 unit = $18 Elyssa's amount of money at first = 4 units = 4 x $18 = $72 (b) Total sum of money = 15 units - $6 = 15 x $18 - $6 = $264

Not sure if the answer is correct

my answer

Har... Is that a primary question

My guess is secondary 2

I think the answer can be simplified further to (2x + 5)/[(2x+1)(x-1)]

Thank you so much... your answer is correct... but is it possible to explain all the steps in a more easier way to understand?

Cauvery, to teach u can assume they are real fractions with numbers instead of variables... hopefully that should help ur child

I don't think is correct but need to verify

Serene Lee you are correct :)

Expand the exponents, then invert fraction due to division sign. After that you are ready to cancel out common terms

Could I know if this is Primary maths question? Which maths level?

No, this is secondary two level

Frighten me lah ... I thought Pri sch maths have this type of questions. There is a secondary two maths group around .. should have post these questions there ....

I feel the same Chan CH... I oversight and thought it is a p5 question.

Thank you so much

Thank you so much
