Question

  

Answer 1

`6/x =15/10`

`=> 6xx10 = x xx15`

`=> 15x=60`

`=>x=60:15`

`=>x=4`

`----`

`x/120=15/24`

`=> 24x=120 xx 15`

`=> 24x= 1800`

`=>x=1800:24`

`=>x=75`

 

Answer 2

\(a,\dfrac{6}{x}=\dfrac{15}{10}\\ \dfrac{6}{x}=\dfrac{3}{2}\\ \dfrac{6}{x}=\dfrac{6}{4}\\ x=4\\ b,\dfrac{x}{120}=\dfrac{15}{24}\\ \dfrac{x}{120}=\dfrac{75}{120}\\ x=75\)

Answer 3

\(\dfrac{6}{x}=\dfrac{15}{10}\)

\(\Rightarrow\dfrac{6}{x}=\dfrac{3}{2}\)

\(\Rightarrow6\times2=3\times x\)

\(\Rightarrow3\times x=12\)

\(\Rightarrow x=4\)

\(\dfrac{x}{120}=\dfrac{15}{24}\)

\(\Rightarrow\dfrac{x}{120}=\dfrac{5}{8}\)

\(\Rightarrow8\times x=120\times5\)

\(\Rightarrow8\times x=600\)

\(\Rightarrow x=75\)

Answer 4

\(\dfrac{6}{x}=\dfrac{15}{10}\)\(=>6\times10=15x\)

\(=>60=15x\)

\(=>x=60:15=4\)

 

\(\dfrac{x}{120}=\dfrac{15}{24}\)

\(=>24x=120\times15\)

\(=>24x=1800\)

\(=>x=75\)
