+ 3/4a . 4/5b
+ a+1/2a-6 : a"+3a+2/a-3
KASIH CARANYA

Answer 1

1/2m + 1/3m
= (3m + 2m) / 6m²
= 5m/6m²
= 5/6m

2(x - 2)/x - 3(x - 1)/x²
= (2x(x - 2) - 3(x - 1))/x²
= (2x² - 4x - 3x + 3)/x²
= (2x² - 7x + 3)/x²

3/4a . 4/5b = 12/20ab
= 3/5ab

(a + 1)/2(a - 3) x (a - 3)/(a + 1)(a + 2)
= 1/2 x 1/(a + 2)
= 1/(2(a + 2))
