G.swimmers + G.non-swimmers = 7, so total number of girls is a multiple of 7

since total number of girls : total number of boys = 6:5

we multiply by 7 to get --> 42 : 35

Sorry could not understand why we need to multiply by 7 [why we need to use G.swimmers and G.non-swimmers ]

Can't we use b.swimmers+b.non-swimmers = 5 instead ?

Hello milo-cupcake,milo-cupcake wrote:Hi,

B : G

1 : 10

3 : 2 (booklets each)

----------

3 : 20, total 23 booklets per 1 boy and 10 girls.

23 x $25 = $575. This means every 1 boy and 10 girls can make $575

Total earnings = $5750

$5750 / $575 = 10 groups of (1 boy and 10 girls)

So,

a) 10 boys

b) 100 girls

hope this helps!

We can see it as pears have 7u in total and apples have 5u in totalmilo-cupcake wrote:Hi ILLUSDUCA,

Sorry another question needs help:

1u of pears and 1u of apples = 26

2u of pears and 2u of apples = 52

5u of pears and 5u of apples = 130 fruits

If 5u of pears and 5u of apples were gone, then only 2u of pears are left

so, 140 - 130 = 10 pears = 2u

1u = 5 pears

7u = 35 pears

hope this helps!

Hi,cftan wrote:850 children took part in a contest. They were divided into two groups.

1/4 of the boys are in Group X and 1/3 of the girls are in Group Y.

There are as many boys as girls in Group Y.

How many boys and how many girls took part in the contest?

Please

Cheers
