«We will present now, — continues Ejtken, — that have asked to translate you in decimal fraction 5/gz - I sraz see, that, having increased numerator and a denominator drob on 3, I will receive equivalent fraction 15/b9, the denominator to toroj comes to an end with rather convenient nine». A feather, the dilemma arises the calculator: to "transform" 69 in 7 (and to divide 1,5 on 7 on just described way or, having increased numerator and a denominator of initial fraction on 13 to transform it in 65/ge9 and to divide then 0,65 on 3 (thus figures from private in a corrected divider will get with "delay" on dvg a sign)

If in game Enona to play with the scraps of a cord connected in loops with perimetre of more than 2 sm that from players who does the second course, without effort provides to itself(himself) a victory. When its opponent will cut off 1 sm from any loop, thereby having transformed it in obych -

There are numerous versions of triangle Paskalja and its generalisations, for example В«tetrahedron PaskaljaВ», in which kind factors of decomposition of "trinomial" (h - \-at-4) the item settle down

14. Nuts and pieces of iron, being in toy lodochke, supersede quantity of the water which weight is equal to their weight. В«Dumped for a boardВ», they fall on a bath bottom, superseding thus quantity of the water which volume is equal to their total volume. As each piece of iron weighs much more the water occupying its volume, the water level in a bath after unloading will go down

In lithograph В«the Ascension and descentВ» (fig. 92) one of the surprising ("impossible") figures which for the first time have been found out English genetikom by L.S.Penrouzom and his son by the mathematician of R

Pieces — on one party at each square. The same it is possible to tell and about eight white squares. However to destroy all 16 squares it is possible, not necessarily having erased 16 individual pieces, and much more economical way. Really, having erased the party dividing a white and dark square, we at once «will kill two hares» — we will destroy perimetres of two squares

The formulas, allowing to define length of a trajectory of a sphere and number of impacts, are intuitively clear from fig. 41 which idea is borrowed from already mentioned book SHtejngauza В«Mathematical kaleidoscopeВ». Irrespective of the integer sizes of a rectangle we can always construct a square, taking big enough number of its "copies" and having arranged them closely to each other (fig. 41)

There is one more multiplier. To find it it is absolutely easy, I skolku in numerator of the fractions entering in required is probable ^! 0, there are consecutive odd numbers. A formula conclusion mozh В»^ to find in the book And. M and And

7. Game in 8. We already repeatedly told about Sam Lojda's well-known puzzle — to game in 15 * | There is a set of similar puzzles. Kashch

For a year N'Pongo has grown almost twice, and I have felt, that it is time to those or different way to get to it to the spouse. I cannot justify zoos (unless they are strongly limited in the finance) which get animals only for display and do not care of family creation by the ward. For anthropoids it is especially important.

At last the Background has gathered home. We looked, how he walks through a wide court yard, from time to time sniffs on the advisers, and all roll with laughter.
