The answer is 60.
Explanation : 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.
Thus, 3 2 × 90 = 60 ;
To calculate 3 2 of 90, multiply 3 2 by 90, which can be written as 3 2 × 1 90 . This results in 3 180 , which simplifies to 60. Hence, 3 2 of 90 is 60.
