$$4 \frac { 7 } { 25 } - 2 \frac { 11 } { 25 } - 3 \frac { 1 } { 25 }$$
$-\frac{6}{5}=-1.2$
$$\frac{100+7}{25}-\frac{2\times 25+11}{25}-\frac{3\times 25+1}{25}$$
$$\frac{107}{25}-\frac{2\times 25+11}{25}-\frac{3\times 25+1}{25}$$
$$\frac{107}{25}-\frac{50+11}{25}-\frac{3\times 25+1}{25}$$
$$\frac{107}{25}-\frac{61}{25}-\frac{3\times 25+1}{25}$$
$$\frac{107-61}{25}-\frac{3\times 25+1}{25}$$
$$\frac{46}{25}-\frac{3\times 25+1}{25}$$
$$\frac{46}{25}-\frac{75+1}{25}$$
$$\frac{46}{25}-\frac{76}{25}$$
$$\frac{46-76}{25}$$
$$\frac{-30}{25}$$
$$-\frac{6}{5}$$
