    1) she uses 13 x 1/4 cups

    as 13 is a whole number multiply the TOP number of the fraction by 13 = 13/4

    then simplify by dividing the TOP number by the BOTTOM number to give whole numbers and the remainder is still a fraction = 3 (as 3 x 4 = 12) and 1/4 left over = 3 and 1/4

    2)to simplify the top heavy fraction divide the TOP number by the BOTTOM number to give the whole number and the remainder stays as a fraction

    13/5 = 2 since (2 x 5 = 10) with 3/5 left over = 2 and 3/5 = answer c

    1. is 3 1/4 because

    you multiply the # of batches by how much is in each (13x1/4 or .25)

    so 13x.25=3.25 or [[3 1/4]]

    2. is 2 3/5 because

    5 goes into 13 2 times( because 5x2=10)

    with 3 left over (so you put the 3 over the 5)

    so 2 and 3/5s left over.

    get it?

    1. Count by 4s to 13: 4, 8, 12, and one left over to get 13. So, 3 and 1/4, answer is B.

    2. Count by 5s to 13: 5, 10, and 3 left over to get 13. So, 2 and 3/5, answer is C.

    1) 1/4=0.25

    0.25x13= 3.25 =

    B: 3 1/4

    2) 13/5 = (1/5 + 1/5 + 1/5 + 1/5 + 1/5) + (1/5 + 1/5 + 1/5 + 1/5 + 1/5) + 1/5 + 1/5 + 1/5

    1st set of brackets: (5/5) = 1 + 2nd set of brackets: (5/5) = 1 + (3/5)

    1+1+ 3/5 =

    C: 2 3/5

    in no way concern, Jaws is right here! The probability of choosing a crimson card from a deck of fifty two playing cards is exactly a million/2, as a results of fact a million/2 of the playing cards are crimson and a million/2 of the playing cards are black. Fractional variety = a million/2 Decimal variety = 0.5 p.c. variety = 50%
