the length of the ribbon was originally 55 cm . it was reduced in the ratio 11 : 7 . what is its length now ?
explanation : length of ribbon originally = 55 cm let the original length be 11 x and reduced length be 7 x . but 11 x = 55 cm x = 55 / 11 cm = 5 cm therefore , reduced length = 7 x cm = 7 5 cm = 35 cm answer : c
multiply(55, divide(7, 11))
