(11)(+1.3)-(+17/7)
(12)(-2)-(+2/3)
(13)|(-7.2)-(-6.3)+(1.1)|
(14)|(-5/4)-(-3/4)|-|1-5/4-|-3/4|)
(15)(-2/199)*(-7/6-3/2+8/3)
(16)4a)*(-3b)*(5c)*1/6
1.3/7×49/9-4/3
2.8/9×15/36+1/27

7.5/2-(3/2+4/5)
8.7/8+(1/8+1/9)
9.9×5/6+5/6
10.3/4×8/9-1/3
0.12χ+1.8×0.9=7.2(9-5χ)×0.3=1.026.4χ-χ=28+4.4
11.7×5/49+3/14
12.6×(1/2+2/3)
13.8×4/5+8×11/5
14.31×5/6–5/6
