Question

prove that 3:8 is equivalent to 12:32

\[3*x=12\]
\[8*x=32\]
So this means that..
\[12/3=4\]
and...
\[32/8=4\]
So x is equal to 4

Answer 2

\(\large {
\begin{cases}
3:8\to \cfrac{3}{8}\\
12:32\to \cfrac{12}{32}
\end{cases}\qquad \cfrac{\cancel{ 12 }}{\cancel{ 32 }}\implies \cfrac{\square ?}{\square ?}
}\)

Answer 3

Cross multiply and the answer should be the same
