You have to use the reciprocal. for example, 4/5 divided by 1/3
you would leave the dividend the same but flip the divisor. you would change it to a multiplication sign. 4/5 times 3/1
then multiply straight across. hope i helped
The answer is the third answer because it is the only option where the number 45 is multiplied by something bigger than 1. If something is multiplied by something smaller than one then it will be smaller than the number multiplied.
Aka: 45x0.8 is 36, because 0.8 is smaller than one
