(2)でなんで9B➕xの1の位が8➕2➕Xになるのかがわかりません

430 基本例題 104] 倍数の判定法 3 (1) 百の位の数が2である3桁の自然数Aがある。 Aが5の倍数であり、 の倍数であるとき、Aを求めよ。 " (2) ある2桁の自然数Bを9倍して45を足すと, 百の位が8, 十の位が2で p.426 基本事項 2 4 あるとき, B を求めよ。 CHART & SOLUTION 倍数の判定法の利用 5の倍数 3の倍数 9の倍数 0 または⑤ の位の数が 解答 各位の数の和が3の倍数 各位の数の和が9の倍数 (2) 計算して出てきた数をCとおくと, Cは3桁の自然数であることを確認する。Cの一 の位の数をxとすると、条件から8+2+xは9の倍数である。 HOTEL A の十の位, 一の位の数をそれぞれx, xとすると Aが5の倍数であるから v=0> またはy=5 Aが3の倍数であるから, 2+x+yは3の倍数である。 0≦x≦であるから、 2+y≤2+x+y≤11+y ・① 11+12...00 =0 のとき, ① は 2≤2+x≤11 *T, 2+x=3, 6, 9 457 x-1, 4.2 St y=5 のとき, ① は 7≦7+x≦16 2. よって, 7+x=9, 12, 15 から x=2,5,8 OGAO D したがって A=210,240, 270, 225,255,285 (2) Bは2桁の自然数であるから 10≤B≤99 よって 9.10+45≤9B+45≤9.99+45 すなわち 135 ≦9B+ 45 ≦936 ゆえに、9B+45 は3桁の自然数であり, 9B+45=9(B+5) であるから9の倍数である。 よって、9B+45 の一の位の数をxとすると, 8+2+x すなわち10+xは9の倍数である。 更に, 0≦x≦9 であるから 10≦10+x≦19 よって, 10+x=18 すなわち x = 8 となり 9B+45=828 したがって B=(828-45)÷9=87 PBACTICE 104② は十の位の数。 100 2以上11以下の整数の 中で3の倍数であるも のを書き出す。 DEREITA-AE 10≦B≦99 の各辺に 9 を掛け、更に45を加え る。 ort. FRONO ←10以上19 以下で9の信 数は18のみ
