Question

What is 34% of 50?

A. 7

B. 17

C. 34

D. 68

Answer 1

\(\bf {\color{red}{ a}}\%\ of \ b=\cfrac{{\color{red}{ a}}}{100}\times b\qquad \qquad {\color{red}{ 30}}\%\ of \ 50=\cfrac{{\color{red}{ 30}}}{100}\times 50\)

Answer 2

If in 100 parts it is 34

then in 50 parts it should be half that amount, that is 17.

Which can be calculated from the formulae @jdoe0001 posted above. :D
