1. convert the values in fractions from decimals.
0.33... = x...(i)
3.33... = 10x...(ii)
subtracting (i) from (ii), we get
9x= 3
x= ⅓
0.44... = x...(iii)
4.44... = 10x...(iv)
subtracting (iii) from (iv), we get,
9x = 4
x= 4/9
therefore,sum of 0.3 + 0.4 = 3/9 + 4/9= 7/9
7/9= 0.77...
2. x²- 3x
=> x(x-3)
x= 3,0
0.33... = x...(i)
3.33... = 10x...(ii)
subtracting (i) from (ii), we get
9x= 3
x= ⅓
0.44... = x...(iii)
4.44... = 10x...(iv)
subtracting (iii) from (iv), we get,
9x = 4
x= 4/9
therefore,sum of 0.3 + 0.4 = 3/9 + 4/9= 7/9
7/9= 0.77...
2. x²- 3x
=> x(x-3)
x= 3,0
