<span>The answer is 60. 
Explanation<span>: 
In mathematics, the word "of" indicates multiply. This means we would multiply 2/3 * 90. 
We can write 90 as a fraction by putting it over 1, which gives us 2/3(90/1). 
To multiply fractions, we multiply straight across: (2*90)/(3*1) = 180/3 = 60.</span></span>
