Solve the problems:
2 1/2 + x = 5 1/3
2 4/15 - z = 1 2/3
y - 6 7/8 = 2 1/16

2 1/2 + x = 5 1/3

x = 5 1/3 - 2 1/2

x = 16/3 - 5/2

x = 32/6 - 15/6

x = 17/6

x = 2 5/6

2 4/15 - z = 1 2/3

-x = 1 2/3 - 2 4/15

-x = 5/3 - 34/15

-x = 25/15 - 34/15

-x = - 9/15

-x = -3/5

x = 3/5

y - 6 7/8 = 2 1/16

y = 2 1/16 + 6 7/8

y = 33/16 + 55/8

y = 33/16 + 110/16

y = 143/16

y = 8 15/16

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
