a piece of rope 60 feet long was cut into twp pieces with lengths that were in the ratio 4:1?

a piece of rope 60 feet long was cut into twp pieces with lengths that were in the ratio 4:1 the shorter of the two pieces was then cut into two pieces with lengths that were in the ratio 2:1 what was the length of the shortest of all these pieces

    Divide the length by the amount of pieces. The ratio is 4:1 (5 pieces)

    60/5 = 12.

    The shortest length for a 12 foot rope at a ratio of 2:1 (3 pieces) is

    12/3 = 4 feet.

    I'll explain why this is so:

    So you have 60 ft and want a ratio of 4:1. A ratio of 4:1 makes five pieces (4 +1 = 5, get it?).

    Since that means five pieces, you must divide your overall length by 5.

    60/5 = 12.

    Now, you want a ratio of 4:1 (which could also be written as 4/1)

    So as a fractional ratio, you may multiply the top and bottom by your singular piece lengths (12 ft).

    That makes 4/1 * 12/12

    Multiply straight across which would be (4*12)/(1*12), giving you 48/12

    Once you have the ratio of 48/12 (48:12) you have the shortest length at 12.

    You repeat the previous steps once again, except using 12 ft, instead of 60.

    2:1 is equal to 3 pieces.

    12/3 = 4.

    So the ratio of 2:1 of 12 ft is equal to 8:4 (8ft to 4ft).

    The shortest length of all these pieces is 4 feet.

    60 in the ratio of 4:1 = 48:12

    12 in the ratio of 2:1 = 8:4

    Shortest length is 4.

    the length were in the ratio 4:1 i.e 48:12

    now the 12m rope is cut into 2:1 ratio so the length of two ropes are 8:4

    the length of the shortest rope among all these is 4ft

    First of all, divide 60 by 5 to get 12, multiply by 4 to get 48. 48+12=60

    12/3=4

    (2+1=3)

    12 feet long rope is the smallest piece

    when a 60 feet long rope is cut into two pieces

    with lengths that are in the ration 4 : 1.

    4x + x = 60

    x = 12 feet

    4x = 48 feet

    the shorter (12 feet) is cut into two pieces in the ratio of: 2 : 1

    2x + x = 12

    x = 4

    the shortest piece is 4 feet...(the other is 8 feet)

    Easy problem...try reading the textbook !

    Suppose the shorter piece = x

    The longer one = 60 - x

    The ratio is …… large ……. 4

    ------- = -------- substituting in terms of x …………………..short …….1

    60 - x 4

    -------- = ------

    x 1

    Cross multiply: 60 - x = 4x + x

    60 = 5x div by 5

    12 = x

    Result: The longer piece is 48 ft ( 4x ), the shorter piece is 12 ft

    60/5=12

    12/3=4

    total length of rope= 60 ft

    it cuts in two pieces with ratio 4:1

    let the pieces are 4k ft & k ft

    so,

    4k ft+k ft=60 ft

    i.e. 5k ft= 60 ft

    i.e. k= 60/5 =12

    so, pieces are of (4*12)ft =48 ft and (1*12)ft=12ft
