1.we should multiply 8/13 with 52 to get 32.
2.a)4/7+(2/9+14/27)=4/7+((6+14)/27)
=4/7+(20/27)
=(108+20)/189
=128/189
b) 3/2(-6/7+1/5)=3/2×-6/7+3/2×1/5
=-9/7+3/10
=-90+21/70
=-69/70
c) 2/7×7/9+-4/18×2/7=2/7(7/9-4/18)
=2/7((14-4)/18)
=2/7(10/18)
=2/7×5/9
=10/63
3. 3/11+2/5=(15+22)/55
=37/55
3/11×2/5=6/55
(37/55)/(6/55)=37/55×55/6
=37/6
5. 3/7+4/9-2/7-8/9-5/7=(3-2-5)/7+(4-8)/9
=-4/7-4/9
=(-36-28)/63
=-64/63
1.a)7x-5=16
7x=16+5
7x=21
x=21/7=3
b)3m+4=8m+24
8m-3m=4-24
5m=-20
m=-20/5=-4
c)11x-4/3=2x+5/3
11x-2x=5/3+4/3
9x=9/3
x=3/9
x=1/3
d)x-(x-2)/7=(9x+7)/2
(7x-x-2)/7=(9x+7)/2
14x-2x-4=63x+49
12x-63x=49+4
51x=53
