Answer:
Nestor needs to buy 7 ½ meters rope
And: the length of the rope that is greater is : 9 meters
Step-by-step explanation:
From the length conversion table:
We know that:
1 meters = 100 centimetres
We are told that Nestor needs 750 centimeters of rope
Now; these ropes comes in the length of 4 ½ meters and 9 meters at the hardware store
To determine the length of rope should Nestor buy? ; we will need to first convert the length of the ropes in meters to centimeters first;
so
4 ½ meters to centimeters = 4 ½ × 100 centimeters = 450 centimeters
9 meters to centimeters = 9 × 100 centimeters = 900 centimeters
And Nestor needs to purchase 750 centimeters of rope;
So if ;
4 ½ meters = 450 centimeters
Then ; let x meters = 750 centimeters
So;
x meters × 450 centimeters = 4 ½ meters × 750 centimeters
x meters = (4 ½ meters × 750 centimeters) / 450 centimeters
x = 7 ½ meters
Also; if
9 meters = 900 centimeters
Then ; let x meters = 750 centimeters
So;
x meters × 900 centimeters = 9 meters × 750 centimeters
x meters = (9 meters × 750 centimeters) / 900 centimeters
x = 7 ½ meters
Thus; Nestor needs to buy 7 ½ meters rope
And: the length of the rope that is greater is : 9 meters
Answer:
Nestor should buy the rope that is 9 meters long
Step-by-step explanation:
Nestor will need to buy a rope that is longer than 750 centimeters so that he can easily cut it to serve his need. If he buys a shorter rope, it will be a lot more difficult to join to get the required length that he needs.
To know the length of his various options and determine the one that is best, we will convert all the ropes to the same unit (cm) and compare is with the required length.
Rope A: 4.5 meters
1 m = 100 cm
4. 5 cm = 4.5 X 100 = 450 cm
This is clearly shorter than is required
Rope B: 9 meters
1 m = 100 cm
9 m = 9 X 100 = 900 cm
This is clearly longer than is required, hence should be Nestor's choice
