Question

20 ribbons, each of length 35 cm, when joined together will give us a ribbon of length ___ m (Put numerical value).

Answer 1

Total length of 20 ribbons
= Length of one ribbon x Number of ribbons
= 35 cm x 20 = 700 cm
Now, we know that 100 cm = 1 m
So, 1 cm = $\frac{1}{100}$ m
$\therefore$ 700 cm = $\frac{700}{100}$ m = 7 m
