If a multiplied by 1 / 5 = B multiplied by 1 / 6, a is greater than 0, B is greater than 0, then the size relationship between a and B

If a multiplied by 1 / 5 = B multiplied by 1 / 6, a is greater than 0, B is greater than 0, then the size relationship between a and B

a*1/5=b*1/6
a:b=1/6:1/5=5:6
Because a is greater than 0, B is greater than 0
So a is less than B
