(ii) 3.375

(iii) 0.2

(iv) 0.153

(v) 0.645

(vi) 0.833

(vii) 0.143

(viii) 0.647

Answer 2

Answer:

i)0.42

ii) 3.375

iii)0.2

iv)0.153

v)0.654

vi)0.833

vii)0.143

viii)0.647

Step-by-step explanation:

I may solve ii) one for uh by full explanation

ii)27/8

factors of is 3times 2

So,

2^3

we can write as 27/2^3

we 5 also in denominat. As we know that in a^n×a^m this is the formula of finding decimal, so we take 5 but the will be same for that we to multiple 5^3 in denominater as well as nominater

so, we write as 27×5^3/2^3×5^3= 3375/1000=3.375

Therefore the answer is 3.375

I hope this well to understand briefly

Thank you
