a)4 b)-9 c)15 d)3/4 e)-8

1) -10 : (-2,5) = 4 2) 8 * (-1[latex] frac{1}{8} [/latex]) = 8 * [latex]( -frac{9}{8}) [/latex] = -[latex] frac{71}{8} [/latex] = 9 3) -2[latex] frac{1}{2} [/latex] * (-6) = -[latex] frac{5}{2} [/latex] * (-6) = [latex] frac{30}{2} [/latex] = 15 4) -3[latex] frac{3}{4} [/latex] : (-6) = -[latex] frac{15}{4} [/latex] * (-[latex] frac{1}{6} [/latex] = [latex] frac{15}{24} [/latex] = [latex] frac{5}{8} [/latex] 5) 12 : (-1[latex] frac{1}{2} [/latex]) = [latex] frac{1}{12} [/latex] * (-[latex] frac{3}{2} [/latex]) = -[latex] frac{3}{24} [/latex] = -[latex] frac{1}{8} [/latex] Myślę, że pomogłam :)
