Answer:
<em>24 children</em>
Step-by-step explanation:
If the length of time, y hours, it takes to put a jigsaw puzzle together is inversely proportional to the number of children, x, this is represented as;
![y \alpha \frac{1}{x}\\y =\frac{k}{x}](https://tex.z-dn.net/?f=y%20%20%5Calpha%20%5Cfrac%7B1%7D%7Bx%7D%5C%5Cy%20%3D%5Cfrac%7Bk%7D%7Bx%7D)
k is the constant of proportionality
If it takes 16 children 6 hours to put the jigsaw puzzle together, this means at x = 16, y = 6
Substitute:
6 = k/16
k = 6*16
k = 96
W are to find number of children needed to put the same jigsaw puzzle together in 4 hours, this is done by substituting k = 96 and y = 4 into the expression y = k/x
y = 96/4
y = 24
<em>Hence it will take 24 children to put the same jigsaw puzzle together in 4 hours</em>
