Question

find the greatest possible length which can be used to measure exactly three cloth pieces of length 1.26 m, 1.98 m & 1.62 M

Answer 1

Answer:

18 cm (0.18 m)

Step-by-step explanation:

Find the greatest possible length which can be used to measure exactly three cloth pieces of length 1.26 m, 1.98 m & 1.62 M

Using 1 m = 100 cm

1.26 m = 126 cm

1.98 m = 198 cm

1.62 m = 162 cm

We will find HCF  of 126 , 198 & 162

126 = 2 * 3  * 3 * 7

198 = 2 * 3 * 3 * 11

162 =  2 * 3 * 3 * 3 * 3

We can see common factor in all three numbers

2*3 *3 = 18

18cm = 0.18 m

18 cm (0.18 m) is the greatest possible length which can be used to measure exactly three cloth piece of Length  1.26 m, 1.98 m & 1.62 M
