Answer 1

$\sqrt{0,81\times 625}-\sqrt{2\frac{1}{4}}=0,9\times25-\sqrt{\frac{9}{4}}=22,5-\frac{3}{2}=22,5-1,5=21$

$\sqrt{0,49\times 225}-\sqrt{1\frac{11}{25}}=0,7\times 15-\sqrt{\frac{36}{25}}=10,5-\frac{6}{5}=10,5-1,2=9,3$

$\sqrt{2\frac{14}{121}\times \frac{4}{25}}-1=\sqrt{\frac{256}{121}\times \frac{4}{25}}-1=\frac{16}{11}\times \frac{2}{5}-1=\frac{32}{55}-\frac{55}{55}=-\frac{23}{55}$

$\frac{\sqrt{147}}{\sqrt{48}} =\sqrt{\frac{147}{48}}=\sqrt{\frac{49}{16}}=\frac{7}{4}=1,75$
