Answer 1

$0.63 = 7 \times 0.09 \\ 0.63 = 7 \times 0.3 \times 0.3 \\ 10.5 = 0.5 \times 21 \\ 10.5 = 0.5 \times 3 \times 7 \\ 2.1 = 7 \times 0.3 \\ 4.20 = 0.2 \times 21 \\ 4.20 = 0.2 \times 3 \times 7 \\ the \: common \: factor \: of \: 0.63 \: \: \: 10.5 \: \: \: 2.1 \: \: \: 4.20 \: \: \: is \: 7 \\ hence \: the lcm \: is \: 7 \: plz \: mark \: as \: brainliest \: ........$
