    This concept will be better understood if we convert the ratios to fraction. Thus, $8:7\rightarrow40:x$ becomes $\dfrac{8}{7}=\dfrac{40}{x}$. Using the concept of equivalent fractions, we multiply both the numerator and the denominator of the left hand side by 5 to get $\dfrac{8\times5}{7\times5}=\dRead more

    This concept will be better understood if we convert the ratios to fraction.

    Thus, 8:7\rightarrow40:x becomes \dfrac{8}{7}=\dfrac{40}{x}.

    Using the concept of equivalent fractions, we multiply both the numerator and the denominator of the left hand side by 5 to get \dfrac{8\times5}{7\times5}=\dfrac{40}{x}\Rightarrow\dfrac{40}{35}=\dfrac{40}{x}.

    By comparison, x=35.
