1.  (i)108.45(ii)0.46
2.  (i)108.35(ii)0.45
3.  (i)208.40(ii)1.46
4.  i)108.35(ii)0.45

Answer 1

(i) 12.05*5.4+0.6



$\huge12.05*5.4+0.6 \\ \\ \\ \huge = > \red {\bf{65.67}}$




(ii) 0.6*0.6+0.6*0.6



$\huge 0.6*0.6+0.6*0.6 \\ \\ \\ \huge = > 0.32 \: + \: 0.32 \\ \\ \\ \huge \bf = > \red{0.72}$

Answer 2

$\red{\huge{\underline{\underline{\sf{A}\mathfrak{nswer}}}}}$



No option is correct.

(i). 65.13
(ii). 0.72



$\huge{\sf{\red{Solution}}}$



$\sf{\blue{(i)\: 12.05 \times 5.4 + 0.6}}$

$\sf{\blue{\implies 65.07 + 0.6}}$

$\sf{\blue{\implies {\boxed{\boxed{65.13}}}}}$



$\sf{\green{(ii)\: 0.6 \times 0.6 + 0.6 \times 0.6}}$

$\sf{\green{\implies 0.36 + 0.36}}$

$\sf{\green{\implies{\boxed{\boxed {0.72}}}}}$
