A) ( 25 / 100 ) * 100 = 25 m ;
b) ( 30 / 100 ) * ( 1205 / 100 ) = 36150 / 10000 = 3615 / 1000 = 3,615 km ≈ 3,62 km ;
c) ( 40 / 100 ) * 60 = ( 4 / 10 ) * 60 = 4 * 6 = 24 m^2 ;
d) 3 1 /3 = 10 / 3 ;
( 32 / 100 ) * ( 10 / 3 ) = 320 / 3 = 106,66 kg;
e) ( 1 / 10 ) ÷ 100 * 10 = ( 1 / 10 ) * ( 1 / 100 ) * 10 = 1 / 100 = 0,01 l ;
Good luck !
i can not give the answer unless you still cannot find it after these steps but I have steps that might help
1. Set the matrix (must be square).
2. Reduce this matrix to row echelon form using elementary row operations so that all the elements below diagonal are zero.
3. Multiply the main diagonal elements of the matrix - determinant is calculated.
