The ratio 140 to m is equivalent to the ratio 4 to 28 . What is

The correct answer is $980$. It's given that the ratio $140$ to $m$ is equivalent to the ratio $4$ to $28$. Therefore, the value of $m$ can be found by solving the equation $\frac{140}{m}=\frac{4}{28}$. Multiplying each side of this equation by $m$ yields $140=\frac{4m}{28}$. Multiplying each side of this equation by $28$ yields $\mathrm{3,920}=4m$. Dividing each side of this equation by $4$ yields $980=m$. Therefore, the value of $m$ is $980$.
