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