Me ajudem pfv é MUITO URGENTE!!!!​

Answer 1

asterisco onde cancela

$a)\frac{5*}{3} .\frac{9}{5*} .\frac{1}{3} = \frac{9}{3}.\frac{1}{3}= 3_*.\frac{1}{3*}=1\\\\b)\frac{12*}{5**}.\frac{10**}{3*}.\frac{2}{4}= \frac{4*}{1}.\frac{2}{1}.\frac{1}{2*}=2.2.1=4\\\\c)\frac{25*}{3**}.\frac{12***}{5*}.\frac{3**}{4***}=\frac{5}{1}.\frac{3}{1}.\frac{1}{1}=5.3=15\\\\d)\frac{16*}{3**}.\frac{27**}{8*}.\frac{1}{5}=\frac{2}{1}.\frac{9}{1}.\frac{1}{5}=\frac{18}{5}\\\\e) 4^*.\frac{6**}{64*}.\frac{1}{12**}= 1.\frac{1}{16}.\frac{1}{2}=\frac{1}{32}$

$f) 5^*.\frac{2**}{27***}.\frac{9***}{4**}.\frac{3}{35*}= 1.\frac{1}{3****}.\frac{1}{2}.\frac{3****}{7}=1.1.\frac{1}{2}.\frac{1}{7}=\frac{1}{14}$
