Hi, could someone pls help with this question:
May had 48 stalks of flowers in a basket. 1/3 of them were roses and the rest were lilies and daisies. There were 4 more lilies than daisies. How many daisies should May buy such that the number of daisies would be 1/2 of the total number of flowers in the basket?
(Thanks) -

If 1/3 were roses, that means 2/3 were lilies and daisies. That mean shat there are 48 x 2/3 = 32 lilies and daisies. If there were 4 more lilies than daisies, that means that there were 14 daisies and 18 lilies. If she wants the daisies to equal half of the basket i.e. 48 x 1/2 = 24, she should buy 24 - 14 = 10 more lilies
Hope you understand

roses --> 1/3 x 48 = 16Hi, could someone pls help with this question:

lilies and daisies --> 48 - 16 = 32
daisies --> (32-4) ÷ 2 = 14
use MD to do the next part.. I will use units here...
Number of daisies to buy --> 1 unit, new total number of daisies --> 1 unit + 14
New total --> 1 unit + 48 --- this is twice the number of daisies
so, 1 unit + 48 = 2 units + 28
1 unit --> 20
May should buy 20 more daisies.
(total number of flowers - 68, daisies - 34)
cheers. -

the question could be solved in a quicker way, using the concept of constant difference/gap.
The difference in total number of daisies and total number of flowers = 48 - 14 = 34
When additional daisies are bought, the same number is added to the total and to the number of daisies --> so, the difference will remain the same.
In the end, the total number of flowers = 2 x number of daisies
since the difference is 34, the total number in the end = 34 x 2 = 68
additional number of daisies to be purchased = 34-14 = 20.

Tan painted 1/4 of a pole red and 1 2/3m of the pole blue. The rest of the pole was not painted. If the pole is 6m long, what was the length of the pole that was not painted?
Can somebody help me… -

1/4 of 6m = 1.5m = 3/2mTan painted 1/4 of a pole red and 1 2/3m of the pole blue. The rest of the pole was not painted. If the pole is 6m long, what was the length of the pole that was not painted?
Can somebody help me.....
Red+Blue = 3/2+5/3 = 19/6m
Not painted = 6 - 19/6 = 2.83m -
Thank u very much…I solved it this way…
Length of the pole=6m
1/4 of 6m= 1.5m
1.5+1 2/3=31/6m painted
6-3 1/6m=2 5/6m not painted… -
