lelunardi1 (-1/4x²y)+(-3/8x²y)+(-9/8x²y) =
-1/4x²y - 3/8x²y - 9/8x²y = mmc 8
2.-1x²y/8 - 1.3x²y/8 - 1.9x²y/8 =
-2x²y - 3x²y - 9x²y / 8 =
-14x²y / 8

(+2/7ky) + (-3/14ky) + (1/7ky) =
+2/7ky - 3/14ky + 1/7ky = mmc 14
2.2ky/14 - 1.3ky/14 + 2.1ky/14 =
4ky/14 - 3ky/14 + 2ky/14 =
4ky - 3ky + 2ky / 14 =
3ky /14
