We have to divide 7/24 ba 35/48 and to reduce the result to the lowest fraction. First we have to change the dividing of the fractions to the multiplication by fliping the second fraction: 7/24 : 35/48 = 7/24 * 48/35 = ( 7 * 48 ) / ( 24 * 35 ) = 336 / 840. Then we can divide both numerator and denominator by 168. ( 336 : 168 ) / ( 840 : 168 ) = 2 / 5. Answer: A. 2 / 5.
