Answer 2

Given : Rachel has a rope of 40m. She gave 12m 53cm to sam 18m 35cm to ron and 9m 7cm to jack.

To find : The length of the remaining rope.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the length of the remaining rope)

First of all, we will be converting all the lengths into cm alone.

So,

• Rachel has = 40m = (40 × 100)cm = 4000cm
• She gave to Sam = 12m 53cm = (12 × 100)cm + 53cm = 1253cm
• She gave to Ron = 18m 35cm = (18 × 100)cm + 35cm = 1835cm
• She gave to Jack = 9m 7cm = (9 × 100)cm + 7cm = 907cm

[As, 1 metre = 100 centimetres]

So, the length of the remaining rope :

= Initial length (that Rachel had) - (length of rope given to Sam + length of rope given to Ron + length of rope given to Jack)

= [4000 - (1253 + 1835 + 907)] cm

= (4000 - 3995) cm

= 5 cm

= (5 ÷ 100) m

= 0.05 m

Hence, 0.05m of rope is still left with Rachel.
