So the question is 45/4÷18/5×20/7+1/4.

First we will do 45/4 ÷ 18/5 then we will do 20/7+1/4

45/4÷18/5

=45/4×5/18 (doing reciprocal)

=225/72

20/7+1/4 (find the LCM of denominator to add)

=80/28+7/28 (the LCM of 7 and 4 is 28)

=87/28

Now we will do multiplication (225/72×87/28)

=19575/2016.

We can reduce this number the answer is 2175/224.
