Answer» $\huge\fbox\color{gray}{Question}$ $\large\bold{Add:\:\:87m,\:27cm\:and\:92m,\:8cm}$ $\small\fbox\color{red}{Before\:to\:the\:answer,\: let's\:recap\:the\:METRIC CONVERSION}$ $\small\underline\bold{Length:}$ $$\Rightarrow1\:cm = 10\:mm\\\Rightarrow1\:DM = 10\:cm\\\Rightarrow1\:m = 100\:cm\\\Rightarrow1\:m=10\:dm\\\Rightarrow1\:km=1000\:m$$ _____________________ $\huge\fbox\color{gray}{Solution}$ $\small\bold{Before\:finding\:the\:sum\:of\:two\:measurements,}$ $\small\bold{first\:we\:have\:to\:make\:sure\:that\:they\:are\:in\:same\:metric\:units.}$ → Here, there are two different units. So we have to convert the greater unit to smaller unit (i.e., metres to CENTIMETRES). $\small\bold{We\:know\:that\:1\:m=100\:cm.\:So,}$ (1).. 87 m = 87 × 100 ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎‎= 8700 cm (2).. 92 m = 92 × 100 ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎= 9200 cm → Now, we can 'cm(s)' with 'cm(s)'. (1).. 8700 cm + 27 cm = 8727 cm (2).. 9200 cm + 8 cm = 9208 cm $\small\bold{Finally,}$ Add 8727 cms with 9208 cms → 8727 + 9208 = $\large\bold{17935\:cms}$ _____________________ $\large\fbox\color{orange}{Additional\:Steps:}$ We can convert 17935 cm to other units. → 17935 cm = 179350 mm → 17935 cm = 1793.5 dm → 17935 cm = 179.35 m → 17935 cm = 0.17935 km _____________________ If you are an app user, don't worry!
