$382 \frac{3}{10} - 191 \frac{87}{100} =(382 + \frac{3}{10} ) - (191 + \frac{87}{100}) =\\\\=382 + \frac{30}{100} -191- \frac{87}{100} =382 -191+ \frac{30}{100}- \frac{87}{100} =\\\\=191+ \frac{30}{100}- \frac{87}{100} =190+ \frac{100}{100}+ \frac{30}{100}- \frac{87}{100} =\\\\=190+\frac{130}{100}- \frac{87}{100} =190+\frac{43}{100}=190\frac{43}{100}\\\\\\382 \frac{3}{10} - 191 \frac{87}{100} =382.3 - 191.87 =382.3 - 191-0.87 =191.3-0.87=\\\\=190+1.3-0.87=190+0.43=190.43$
