Answer 1

(3 2/3+5 3/5)*x=6 19/20
(3 10/15+5 9/15)*x=6 19/20
8 19/15 *x=6 19/20
9 4/15*x= 6 19/20
139/15*x= 139/20
x=139/20 *15/139
x=15/20
x=3/4

w* 9 1/10= 1 3/4+5 5/6
w* 9 1/10= 1 9/12+ 5 10/12
w*9 1/10= 6 19/12
w* 9 1/10= 7 7/12
w* 91/10= 91/12
w= 91/12 * 10/91
w=10/12
w=5/6

y*(7 9/10-2 3/5)=2 9/22
y*(7 9/10-2 6/10)=2 9/22
y* 5 3/10= 2 9/22
y* 53/10= 53/22
y=53/22 * 10/53
y=10/22
y=5/11

2 1/3*z=4 3/8-2 1/3
2 1/3*z= 4 9/24- 2 8/24
2 1/3*z= 2 1/24
7/3 *z= 49/24
z= 49/24 * 3/7
z= 7/8

( 4 1/7- 2 3/4) *a= 3/28
(4 4/28- 2 21/28) *a= 3/28
(3 32/28- 2 21/28) *a= 3/28
1 11/28*a= 3/28
a=3/28 *28/39
a= 1/3

6 5/9*b= 7 1/3-6 7/9
6 5/9*b= 7 3/9-6 7/9
6 5/9*b= 6 12/9- 6 7/9
6 5/9*b=5/9
59/9 *b=5/9
b=5/9 * 9/59
b=5/59
