Question

if a/b=c/d , then a/d =b/c then this process is called​

Answer 1

answer:-

A ratio remains the same if both antecedent and consequent are multiplied or divided by the same non-zero number,

∘ a/b=pa/pb=qa/qb,p,q



=0

∘ a/b=(a/p)/(b/p)=(a/q)/(b/q),p,q



=0

∙ Two ratios in their fraction notation can be compared just as we compare real numbers.

∘ a/b=p/q⇔aq=bp

∘ a/b>p/q⇔aq>bp

∘ a/b<p/q⇔aq<bp

∙ If two ratios a/b and c/d are equal

∘ a/b=c/d⇒b/a=d/c (Invertendo)

∘ a/b=c/d⇒a/c=b/d (Alternendo)

∘ a/b=c/d⇒(a+b)/b=(c+d)/d (Componendo)

∘ a/b=c/d⇒(a−b)/b=(c−d)/d (Dividendo).

if a/b=c/d , then a/d =b/c then this process is called invertendo
