Mathematics: At a summer camp the campers can choose one of three programmes: camp craft, water sports or hiking. During the first week of camp the campers chose the programmes in the ratio 7:5:8. During the second week of camp the same number of campers chose the programmes in the ratio 7:6:4. Did more campers choose the camp craft programme in the first or second week? How many more?

Second week

Step-by-step explanation:

Given

In first week, campers choose programmes in the ratio of 7:5:8

In second week, this ratio becomes 7:6:4

Suppose 100 campers Joined the camp

Number of hikers who choose camp craft in first week are

$\Rightarrow \dfrac{7}{7+5+8}\times 100=\dfrac{7}{20}\times 100\\\\\Rightarrow 35$

Number of hikers who choose camp craft in second week are

$\Rightarrow \dfrac{7}{7+6+4}\times 100=\dfrac{7}{17}\times 100\\\\\Rightarrow 41.17\approx 41$

Therefore, in second week more campers take part in camp craft.

If 100 campers take part then, 6 more campers takes part in camp craft.

Yes

Step-by-step explanation:

First we have to get the area of the square when the length is 12cm. We know a square has equal sides so we can simply do l * l to get the area.

12 * 12 = 144.

Let's compare this to 170.

170 > 144, so yes we will have enough to make a 12 by 12 handkerchief :)
