Answer 1

Answer:

The length of the ribbon roll from which smaller ribbons are cut = 39.2 cm

The length of each small ribbons = 1.4 cm

To find:

The number of ribbons each of length 1.4 cm long

Solution:

To find the number of ribbons we are given the length of the roll of the ribbon and the length of each small ribbons that are to be cut from the roll.

So, to find the no. of ribbons we can use the following formula:

\boxed{\boxed{\bold{Length\: of\: the \:ribbon\: roll = n \:\times\: [length\: of\: each\: small\:ribbons]}}}

where

n = no. of ribbons

Now, by substituting the given values in the formula, we get

39.2 = n \times 1.439.2=n×1.4

⇒ n = \frac{39.2\:cm}{1.4\:cm}n=1.4cm39.2cm

⇒ \bold{n = 28}n=28

Thus, the number of ribbons each of length 1.4 cm long that can be cut from the ribbon roll, 39.2 cm long is 28.
