136.68+16.272

Answer 1

\(136.68+16.272=136.2.34+16.272\)

\(=272.34+16.272=272.\left(34+16\right)=272.50=13600\)

Answer 2

\(136\cdot68+16\cdot272=136\cdot68+16\cdot2\cdot136=136\cdot\left(68+32\right)=13600.\)

Answer 3

\(136.68+16.272\)

\(=136.2.34+16.272\)

\(=272.34+16.272\)

\(=272\left(34+16\right)\)

\(=272.50\)
