a) -⅘×3¾+4,5÷(-1,5)=
B) (-1⅙)x(-²/₇)+ 12,4 przez(kreska ułamkowa) -37,2=
bardzo proszę o pomoc.
a) -4/5 x 3 ³/₄ + 4,5 : (-1,5) = -4/5 x 15/4 ₄+ (-3) = -3 + (-3) = -6
b) -7/6x(-2/7)+12,4 1/3+12,4 1/3+12⁴/₁₀ ¹⁰/₃₀+12¹²/₃₀
________________ = _______ = _____________ = _____________
-37,2 -37,2 -37²/₁₀ -³⁷²/₁₀
12²²/₃₀
= ___________ = 382/30 x (-10/372) = - 191/558
-³⁷²/₁₀
