Всего частей 2 + 23 = 25
25 - это 100%
2 - это х%
х = 2 : 25 · 100 = 8(%)
Ответ: хвойные деревья составляют 8%

WHAT IS BAD BEHAVIOUR?
People have very different ideas about good and bad behaviour. What is acceptable
in one family can be quite the opposite in another. If you feel you have a problem with
your child’s behaviour, think carefully about whether it might really be your problem.
It is never naughty or dirty for small children to wet or soil themselves. It takes
at least 18 months for children to control their bladder and bowels. Two and a half
to three years is a reasonable age for them to be potty trained. It’s not naughty to feel jealous. It’s only natural for children who have been used to being the centre of attention to feel jealous of a new arrival, for example. Very young children are rarely capable of sharing unselfishly. This is something they have to learn. So don’t expect too much too soon. Crying is not naughty. It’s your child’s way of expressing his feelingsto you. If a small child hurts an adult perhaps by pulling his hair or poking
in the eye, this is either accidental or a natural curiosity to see what happens. Your child doesn’t know that it hurts you, and you should never be tempted to hurt your child in return. If your child seems to be trying to get attention by being naughty, think whether you are giving him enough attention at other times. Try not to have too many confusing rules. Your child will want to make some decisions on his own. You don’t always have to prove that you’re the boss. It is quite natural to a small child to have times when he or she appears to prefer one parent and reject the other. And always remember that children learn more by example than by words. So it is a waste of time telling your child not to do something if you then go ahead and do it yourself.-
