Question

Henry divided his socks into five equal groups. Let s represent the total number of socks. Which expression and solution represent the number of socks in each group if ? ; when , the number of socks in each group is 4. ; when , the number of socks in each group is 15. ; when , the number of socks in each group is 4. ; when , the number of socks in each group is 15.

Answer 1

So for each group just multiply the number of socks in each group to 5 and = s
so
1. s = 4x5
s = 20
2. s = 15 x 5
= 75
the other 2 is duplicated (?) :/

Answer 2

Answer: There are 20 socks in the first case and there are 75 socks in the second case.

Step-by-step explanation:

Since we have given that

Number of equal groups = 5

Let the total number of socks be 's'.

According to question, expression will be

$\text{Number of socks in each group }=\frac{s}{5}$

Now, Suppose number of socks in each group = 4

So, it will become,

$4=\frac{s}{5}\\\\4\times 5=s\\\\20=s$

Suppose number of socks in each group = 15

So, Total number of socks become

$15=\frac{s}{5}\\\\15\times 5=s\\\\75=s$

Hence, there are 20 socks in the first case and there are 75 socks in the second case.
