16 1/2 x 33 = is it 792

  • 3rd grade math -

    16*2+1 = 33
    so 16 1/2 = 33/2

    so
    33*33/2 = 544.5

    I do not think that is third grade math so suspect a typo.

  • 3rd grade math -

    No.

    One way to solve this problem is like this:

    (1/2) * (33/1) = 33/2 = 16 1/2

    16 * 33 = 528

    528 + 16 1/2 = 544 1/2

    You could also use 16.5 for 16 1/2 and multiply. The answer is the same: 544.5

  • 3rd grade math -

    (16 1/2)x33= 16*33+(1/2)*33=

    528+33/2=

    528+(32+1)/2=

    528+16+(1/2)=544 1/2

  • 3rd grade math -

    528+(32+1)/2= 528+(32/2)+(1/2)528+16+(1/2)=544 1/2

  • 3rd grade math -

    528+(32+1)/2= 528+(32/2)+(1/2)=528+16+(1/2)=544 1/2
