Question 678852


{{{90m}}} long into two pieces {{{x}}} and {{{y}}} in the ratio {{{2:3}}}:

{{{x:y=2:3}}}

the ratio {{{2:3}}} means you need divide {{{90m}}} by {{{5}}} to find out what is a length that you will multiply by {{{2}}} to find {{{x}}}, and by {{{3}}} to find {{{y}}}

{{{x=(90m/5)2}}}

{{{x=36m}}}


{{{y=(90m/5)3}}}

{{{y=54m}}}

check is the ratio of these lengths same as the ratio {{{2:3}}}


{{{x:y=2:3}}}

{{{36cross(m)/54cross(m)=2/3}}}

{{{36/54=2/3}}}

{{{0.66666666666666666666666666666667=0.66666666666666666666666666666667}}}..so, this confirms our answer
