jika a = 2/3 dan b 3/4 maka nilai dari 2a+4b / 5a-2b =

a = 2/3
b = 3/4

(2a + 4b) / (5a - 2b)
= (2 x 2/3 + 4 x 3/4) / (5 x 2/3 - 2 x 3/4)
= (4/3 + 3) / (10/3 - 3/2)
= (13/3) / (20/6 - 9/6)
= (13/3) / (11/6)
= 13/3 x 6/11
= 26/11
= 2 4/11

dik, a = 2/3
b = 3/4
dit, (2a + 4b)/(5a - 2b)
penyelesaian:
= [2(2/3) + 4(3/4)]/[5(2/3) - 2(3/4)]
= (4/3 + 3)/(10/3 - 3/2)
= [4/3 + 9/3]/[20/6 - 9/6]
= (13/3)/(11/6)
= 13/3 × 6/11
= 13/1 × 2/11
= 26/11
= 2 4/11
