The following problem is to write the calculation process: one minus two fifths =? Five fifths minus fourteen fifths =? Eight ninths minus five sixths =? One sixth and three eighths =? Solving equation: (write calculation process) Half plus x = 5 / 6 x minus 7 / 10 = 1 / 5 x plus 1 / 4 = 1 / 2

The following problem is to write the calculation process: one minus two fifths =? Five fifths minus fourteen fifths =? Eight ninths minus five sixths =? One sixth and three eighths =? Solving equation: (write calculation process) Half plus x = 5 / 6 x minus 7 / 10 = 1 / 5 x plus 1 / 4 = 1 / 2

One minus two fifths = 3 / 5
Five out of seven minus five out of fourteen = 10 / 14-5 / 14 = 5 / 14
Eight out of nine minus five out of six = 16 / 18-15 / 18 = 1 / 18
One sixth plus three eighths = 4 / 24 + 9 / 24 = 13 / 24
One half plus x = five sixths
x=5/6-1/2
x=1/3
X minus seven tenths = one fifth
x=7/10+1/5
x=9/10
X plus a quarter = half
x=1/4+1/2
x=3/4
