Question

负99又71/72×36= -13×2/3-0.34×2/7+1/3×（-13）-5/7×0.34

Answer 1

解：依题意得算式，
-99又72分之71×36
=（-99-72分之71）×36
=-99×36-72分之71×36
=（-100+1）×36-2分之71
=-100×36+36-35.5
=-3600+0.5
=-3599.5
-13×3分之2-0.34×7分之2+3分之1×（-13）-7分之5×0.34
=-13×（3分之2+3分之1）-0.34×（7分之2+7分之5）
=-13×1-0.34×1
=-13-0.34
=-13.34
即-99又72分之71×36=-3599.5
-13×3分之2-0.34×7分之2+3分之1×（-13）-7分之5×0.34=-13.34

Answer 2

负99又71/72×36
=(1/72-100)x36
=1/72x36-100x36
=0.5-3600
=3599.5
-13×2/3-0.34×2/7+1/3×（-13）-5/7×0.34

=-13x2/3-0.34x2/7-1/3x13-0.34x5/7
=-(26/3+13/3)-0.34x(2/7+5/7)
=-13-0.34
=-13.34
