Sederhanakanlah bentuk penjumlahan dan pengurangan alajabar berikut

a. 3/b + 5/b
=3+5/b
=8/b
b. 4/e - 6/b
=b*4 / eb - e*6 / eb
=4b/eb -6e/eb
=4b-6e / eb
c. 1/a +2x/b-3/c
=bc*1/bca + ac*2x/acb - ab*3/abc
=bc/abc + 2acx/abc - 3ab/abc
=bc+2acx-3ab/abc
d. 3a/4b * 5b/2ab²
=3/4 * 5/2b²
=15/8b²
e. 16x²/y : x/8y²
=16x²/y * 8y²/x
=16x * 8y
=128xy
