The answer is B)5 2/5 Explain n= (2 1/4)/x=(1 1/2)/(3 3/5) we should change is to easy fraction (9/4)/x=(3/2)/(18/5)
(9/4)=2.25 (3/2)=1.5. (18/5)=3.6
Substitute those fraction number with decimal number that makes easy to calculate 2.25/x=1.5/3.6 now we should do cross multiple That means 2.25*3.6=8.1 1.5*x= 1.5x 8.1=1.5x divide both side with 1/5 X=5.4 Back to the choice B, 5 2/5 First multiply 5*5 then add 2 === 27/5 27/5=5.4 So the answer is B
