A.1/3 (2/5 -1/4) ÷ 3/5 =
1/3 X 3/20 ÷ 3/5 =
(1/3 X 3/20) ÷ 3/5 =
1/20 ÷ 3/5=
1/12
B.3/4 ÷ 9/2 + 1/2 (3/5 -1/3) =
(3/4 ÷ 9/2) + 1/2 (3/5 -1/3) =
1/6 + 1/2 (3/5 -1/3) =
1/6 + 1/2 X 4/15 =
1/6 + 1/2 X 4/15=
1/6 + 2/15 =
3/10
C. (8/5 ÷ 5/4) ÷ (7/2 +7/5) =
1 7/25 ÷ 4 9/10 =
64/245
D. 13/4 ÷ (9/2 - 7/3) + 5/4 =
13/4 ÷ (2 1/6 + 5/4) =
13/4 ÷ 3 5/12 =
78/287

15% = 15 out of one hundred = 15/one hundred = 0.15 So, 15% of $608 = 15% X $608 = 0.15 X $608 = $ ninety one.2 So, answer could be $ninety. in simple terms remember what p.c. skill. "in line with" + "Cent". Cent = one hundred, so, p.c. skill out of one hundred. If out of one hundred, that's 15, then out of 608, that's 608 *(15/one hundred)
