Each knive costs £0.60 and each fork costs £0.5

Explanation:

Let's recall knives' price as $x$ and forks' price as $y$.
Then we get these 2 equations:
$4 x + 5 y = 4.90$
$7 x + 3 y = 5.70$

There are plenty of ways to solve this, choose which you like the most.

Finally we get:
$x = 0.6$
$y = 0.5$
