if a / b = 4 / 5 , then ( 5 a - 3 b ) / ( 5 a + 3 b ) = ?
"answer dividing numerator as well as denominator by b , we get given exp . = ( 5 a - 3 b ) / ( 5 a + 3 b ) = ( 5 a / b - 3 ) / ( 5 a / b + 3 ) since a / b = 4 / 5 this implies that = [ ( 5 * 4 ) / 5 - 3 ] / [ ( 5 * 4 ) / 5 + 3 ) ] = ( 4 - 3 ) / ( 4 + 3 ) = 1 / 7 option : e"
divide(add(multiply(5, const_4.0), multiply(3, 5)), subtract(multiply(5, 4), multiply(3, 5)))
