    I'll do the first one:

    8 * 5 = 40

    I'll be glad to check your answers for the others.

    The second is correct. 35/5

    The third one isn't 15 and 20.

    Is 14 19/39 closer to 15?

    Look more carefully at 19/39

    i have a hard time with fractions. would i divide 19/39 to get .48 and round up to get .50 which would be 14 and .50 to go up to 15 and say 15/.5? thanks for your help.

    You're on the right track.

    However, 19/39 is still less than half.

    I'd round one of these fractions up and the other down to get -- 14/1 = 14
