Question

find the greatest possible length which can be used to measure exactly the length 7m, 3m,85cm and 12m, 95cm

Answer 1

Lengths
= 7×100cm=700cm
= 3×100=300
=300-85=285cm
and
12×100+95 = 1295 cm

Required Length
= HCF of (700 cm, 385cm and 1295cm)=35 cm.

Answer 2

Answer:

$|hey \: mate \: here \: is \: ur \: ans|$

$7 \times 100 \: cm \: = 700 \: cm$

$3 \times 100 \: cm \: = 300 \: cm$

$300 - 85 = 285$

$12 \times 100 + 95 \\ = 1295 \: cm$

$required \: length =$

$hcf \: of \: (700 \: cm \: 385 \: cm \: and \: 1295 \: cm$
