Question

Cine mă ajuta dau 30 puncte !!!!

Answer 1

a) (12/25:4/5):9/35
=(12/25*5/4):9/35
=3/5:9/35
=3/5*35/9
=3/7h

b) 12/25:(4/5:9/35)
=12/25:12/7
=12/25*7/12
=7/25

Answer 2

$A) (\frac{12}{25}:\frac{4}{5}):\frac{9}{35}= =(\frac{12x5}{25x4})x\frac{35}{9} =\frac{3}{5}x \frac{35}{9} = \frac{7}{3}$ 

B) $\frac{25}{12}x(\frac{5}{4}x\frac{9}{35})= =\frac{25x3}{4x4x7} =\frac{75}{112}$

C) $\frac{25x16}{36x7}:\frac{60x7}{49x162} = \frac{25x16x49x162}{36x49x60} = \frac{25x16x81}{36x30} =\frac{25x4x9}{30} =\frac{5x4x3}{2} =\frac{5x2x3}{1} = 30$

D) $\frac{11x18x33}{12x13x22}= =\frac{9x33}{12x13}= =\frac{9x11}{4x13} =\frac{99}{52}$
