tolong jawab ya pake caranya 1-10

(1).3/25 = 3/25 × 4/4 = 12/100 = 0,12
(C. 0,12)

(2).0,20 = 20/100 = 1/5
(B.1/5)

(3).2,5% = 0,025 (B. 0,025)

(4).( A. 1/5 )

(5). 1/3 + 2 1/4 = 4/12 + 2 3/12 = 2 7/12
(D. 2 7/12)

(6). 0,5 + 75% - 1/5
=5/10 + 75/100 - 1/5
= 50/100 + 75/100 - 20/100
= 105/100 = 1 5/100 = 1 1/20
(C. 1,05)

(7). 4 1/3 - 2 5/6 = 4 2/6 - 2 5/6
= 3 8/6 - 2 5/6 = 1 3/6 = 1 1/2
(D. 1 1/2)

(8). 2/5 + 0,75 = 2/5 + 75/100
= 40/100 + 75/100 = 135/100 = 1 35/100
= 1 7/20 (D)

(9) 2,5 + 20,6 - 17,75 = 5,35(A)

(10).1 3/5 × 2 1/8= 8/5 × 17/8 = 17/5 = 3 2/5(D)
