Question

What must be added to each term of the ratio 2:5 so that it maay be equal to 5:6

Answer 1

Let the adding value be x

ATQ

$\\ \sf\longmapsto \dfrac{2+x}{5+x}=\dfrac{5}{6}$

$\\ \sf\longmapsto 6(2+x)=5(5+x)$

$\\ \sf\longmapsto 12+6x=25+5x$

$\\ \sf\longmapsto 6x-5x=25-12$

$\\ \sf\longmapsto x=13$
