Answer:

Question :-

100:121::141:?

Solution:-

Let the unknown value be x

Rewrite the ratio

$\\\qquad\quad\sf {:}\rightarrowtail 100:121::141:x$

• convert

$\\\qquad\quad\sf {:}\rightarrowtail 100:121=141:x$

• convert to fraction

$\\\qquad\quad\sf {:}\rightarrowtail \dfrac {100}{121}=\dfrac {141}{x}$

$\\\qquad\quad\sf {:}\rightarrowtail 100x=141×121$

$\\\qquad\quad\sf {:}\rightarrowtail 100x=17061$

$\\\qquad\quad\sf {:}\rightarrowtail x=\dfrac {17061}{100}$

$\\\qquad\quad\sf {:}\rightarrowtail x=170.61$

$\\\qquad\quad\sf {:}\rightarrowtail x=170_{(Approx)}$

$\therefore\sf 100:121::141:170$
