3 3 9 _ x __ =___ 1 10 10 first, change 3 to 3/1 to make multiplying easier. then multiply both fractions(3*3=9,1*10=10) and you get 9/10! this can not be simplified.
The first thing to do is convert 3 into a decimal. The equation is now 3/1 X 3/10. Now you need to find the lowest common multiple of 1 and 10, which is 10. 10 / 1 = 10. 3 X 10 = 30. The question is now 30/10 X 3/10. 30 X 3 = 90. 10 X 10 = 100. 3 X 3/10 = 3/1 X 3/10 = 30/10 X 3/10 = 90/100 = 9/10.
