Question

ayudaaaaaaaa plisssss doy coronita

Answer 1

Respuesta: 27/16 Y 38/9

Explicación paso a paso:

A=(9/20)/(3/10)=3/2

B=(1/12)/(4/9)=3/16

A+B=27/16

Q=8/3

P=14/9

Q+P=38/9

Answer 2

Respuesta:

$A+B = \frac{27}{16}$

$Q + P = \frac{38}{9}}$

Explicación paso a paso:

5.

$A = \frac{\frac{1}{4} +\frac{1}{5} }{\frac{3}{10} } \\A = \frac{\frac{5(1)+4(1)}{(4)(5)} }{\frac{3}{10} }\\A = \frac{\frac{9}{20} }{\frac{3}{10} }\\\\A = \frac{9(10)}{20(3)} \\A= \frac{90}{60} \\A = \frac{3}{2}$

$B = \frac{\frac{1}{3} -\frac{1}{4} }{\frac{4}{9} } \\B = \frac{\frac{4(1)-3(1)}{(3)(4)} }{\frac{4}{9} }\\B = \frac{\frac{1}{12} }{\frac{4}{9} }\\\\B = \frac{1(9)}{12(4)} \\B= \frac{9}{48} \\B = \frac{3}{16}$

$A+B = \frac{3}{2} +\frac{3}{16} \\A+B = \frac{3(16)+3(2)}{2(16)}\\A+B = \frac{48+6}{32}\\A+B = \frac{54}{32}\\A+B = \frac{27}{16}$

6.

$Q = {\frac{1}{3} +\frac{7}{3} }\\Q = {\frac{1+7}{3} }\\Q = \frac{8}{3}$

$P = \frac{2}{3} x\frac{14}{6}\\P = \frac{(2)(14)}{(18)} \\P = \frac{28}{18}\\P=\frac{14}{9}$

$Q + P = \frac{8}{3} +\frac{14}{9} \\Q + P = \frac{8(9) + 3(14)}{3(27)}\\\\\\Q + P = \frac{38}{9}}$
