Answer:
1.33/50=3/(25×2)=3/(5^2 × 2^1)
As the denominator of the given fraction can be expressed in the form 2^m ×5^n,so it is a terminating decimal.
now,
33/(5^2 × 2)= (33×2)/(5^2×2^2)=66/100=0.66
2.625 can be expressed as 5^4 × 2^0 ( 2^m × 5^n. )So it's also a terminating decimal.
11/625=(11×2^4)/(625×2^4)=(11×16)/(625×16)=176/10000=0.0176
Q.no.- 3 & 4 are both terminating & have terminating decimal expressions.So find it out for yourself.
