1550 meters\text{1550 meters}

c

375 meters\text{375 meters}

Step-by-step solution

6 steps

Part a· 2 steps

  1. Identify the initial length of rope and the length used.

    Thandi bought 100 meters of rope.
    Thandi used 75 meters of rope.

  2. Subtract the used length from the initial length to find the remaining length.

    100 m−75 m=25 m100 \text{ m} - 75 \text{ m} = 25 \text{ m}

    The length of rope still left is 25 meters\boxed{\text{25 meters}}.

Part b

1550 meters\text{1550 meters}

  1. Identify the length of rope bought by Father and Mother.

    Father bought 800 meters of rope.
    Mother bought 750 meters of rope.

  2. Add the lengths of rope bought by Father and Mother to find the total length.

    800 m+750 m=1550 m800 \text{ m} + 750 \text{ m} = 1550 \text{ m}

    They have 1550 meters\boxed{\text{1550 meters}} of rope altogether.

Part c

375 meters\text{375 meters}

  1. Identify the total length of rope the children had and the number of children.

    Total rope: 1500 meters.
    Number of children: 4.

  2. Divide the total length of rope by the number of children to find how much each child gets.

    1500 m4=375 m\frac{1500 \text{ m}}{4} = 375 \text{ m}

    Each child will get 375 meters\boxed{\text{375 meters}} of rope.
