Question

tìm x:

4/5x3/7xX/3=24/105

Answer 1

       \(\frac{4}{5}\)\(\times\)\(\frac{3}{7}\)\(\times\)\(\frac{x}{3}\)=\(\frac{24}{105}\)

= \(\frac{4\times3}{5\times7}\)\(\times\)\(\frac{x}{3}=\frac{24}{105}\)

=\(\frac{12}{35}\times\frac{x}{3}=\frac{24}{105}\)

\(\Rightarrow\frac{x}{3}=\frac{24}{105}:\frac{12}{35}\)

=\(\frac{x}{3}=\frac{2}{3}\)

Vậy X = 2

Answer 2

4/5 x 3/7 x X/3 = 24/105

    12/35 x X/3 = 24/105

                 X/3 = 24/105 : 12/35 

           X/3       =    2/3 

          X          =   2/3 x 3

       X             =       2 

Answer 3

4/5x3/7xX/3=24/105

12/35xX/3=24/105

X/3=24/105:12/35

X/3=2/3

=> x=2

Vậy x=2

tk cho mk nha

Answer 4

\(\frac{4}{5}\)x \(\frac{3}{7}\)x \(\frac{x}{3}\)= \(\frac{24}{105}\)

\(\frac{12}{35}\)x \(\frac{x}{3}\)= \(\frac{24}{105}\)

\(\frac{x}{3}\)= \(\frac{24}{105}\): \(\frac{12}{35}\)

\(\frac{x}{3}\)= \(\frac{2}{3}\)

=> x=2
