lo necesito para hoy pls​

Answer 1

Respuesta:

a= 84/7

b=90/4

c= 44/6

Explicación paso a paso:

7/1*12/7

7*12= 84

1*7=7

9/1*10/4

9*10=90

1*4=4

4/1* 11/6

4*11=44

1*6=6

Answer 2

Respuesta:

$7\times \frac{12}{7}=\frac{7}{1}\times \frac{12}{7}$

$\frac{12}{1}=12$

$R=\boxed{12}$

$9\times \frac{10}{4}=9\times \frac{2\times \:5}{4}$

$9\times \frac{2\times \:5}{2\times \:2}=9\times \frac{5}{2}$

$\frac{9}{1}\times \frac{5}{2}=\frac{9\times \:5}{1\times \:2}$

$\frac{45}{1\times \:2}=\frac{45}{2}$

$R=\boxed{\frac{45}{2}}$

$4\times \frac{11}{6}=\frac{4}{1}\times \frac{11}{6}$

$\frac{2\times \:2}{1}\times \frac{11}{6}=\frac{2\times \:2}{1}\times \frac{11}{2\times \:3}$

$\frac{2}{1}\times \frac{11}{3}=\frac{2\times \:11}{1\times \:3}$

$\frac{22}{1\times \:3}=\frac{22}{3}$

$R=\boxed{\frac{22}{3}}$
