Question

1 : a/b :a/b =16

Answer 1

1 : a/b : a/b = 1 . b/a . b/a = b/a^2

Ta có: 16 = 4^2

Vậy b/a = 4.

Answer 2

\(1:\frac{a}{b}:\frac{a}{b}=16\)

\(=1.\frac{b}{a}.\frac{b}{a}=16\)

\(=1.\left(\frac{b}{a}\right)^2=16\)

\(\left(\frac{b}{a}\right)^2=16:1\)

\(\left(\frac{b}{a}\right)^2=16\)

\(\Leftrightarrow\left(\frac{b}{a}\right)^2=4^2\)

\(\Rightarrow\frac{b}{a}=\frac{4}{1}\)

\(\Rightarrow\frac{a}{b}=\frac{1}{4}\)

Answer 3

Ai k mình mình k lại.

Answer 4

=1:\(\frac{a}{b}.\frac{b}{a}\)=16

=1.\(\frac{b}{a}.\frac{b}{a}\)=16

=\(\frac{b}{a}.\frac{b}{a}\)=16:1=16

mà \(\frac{b}{a}=\frac{b}{a}\)

->\(\frac{b}{a}=4\\ ->\frac{a}{b}=\frac{1}{4}\)
