Answer 1

15)
Le calculam pe rand

[(5x70-12x8)x2+7x6]:10+11
=[(350-96)x2+42]:10+11
=(254x2+42):10+11
=(508+42):10+11
=550:10+11
=55+11
=66

[(372:6+2):8x15+39:13]:3
=[(62+2):8x15+3]:3
=(64:8x15+3):3
=(8x15+3):3
=(120+3):3
=123:3
=41

(56:8+15)x9
=(7+15)x9
=22x9
=198

164:(3x120:9-36)
=164:(360:9-36)
=164:(40-36)
=164:4
=41

$\frac{66}{41} < \frac{198}{41}$
66<198
