For one uniform 15/4 m of cloth is needed, since we need 26 uniforms week need 26 time that much cloth. Set up and multiply the equation like so...
*26
or you can write it like so...

Multiply numerator by numerator and denominator by denominator...


^^^This can be further simplified to...
m
or
97.5 m
Hope this helped!
