Question

Betty bought a reelof thread for sewing that is 14.5 m long for a project that she used 425 Centimeters how much thread in meters is left on the reel

Answer 1

Given,

The total length of the thread = 14.5 metres

She used 425 centimetres of thread.

To find,

The length of the remaining thread in metre unit.

Solution,

First of all, we have to convert the total length of the thread into centimetres unit for an easier mathematical calculation.

Total length of the thread

= 14.5 metres

= 1450 centimetres

(Term of unit conversion = 1 m = 100 cm)

Now, we have to calculate the remaining amount of thread by using the following mathematical formula.

= (Total length - used length)

= 1450 - 425

= 1025 cm

= 10.25 m

Hence, the length of the remaining thread is 10.25 metres.
