Question

please give me answer with explaination​

Answer 1

Answer:

238 bookmarks ( approx )

Step-by-step explanation:

Length of each bookmarker  = 10.5 cm

Total length of ribbon = 15m

Number of bookmarker = Total length of the ribbon in cm

                                            __________________________

                                              Length of each bookmark in cm

Total length of the ribbon = 25m = 2500cm

Length of each bookmark = 10.5cm

Number of bookmark = $\frac{2500}{10.5}$

Removing decimal places-

= $\frac{2500}{10.5} * \frac{10}{10}$

=$\frac{25000}{105}$

= $\frac{5000}{21}$

= 238.09

you can round of the answer to get -

= 238 bookmarks ( approx )

hope it helps..

Answer 2

Solution:-

Given :-

a) ribbon is 25m long

b) width of ribbon is 10.5 cm (given in fig)

Find :-

a) how many bookmarks raju can make from 25 m ribbon.

now,

we know 1 m = 100 cm

so, 25 m = 2500 cm .....( 1 )

To find how many bookmarks raju can make from 25 m ribbon.

let, bookmarks be, X

Hence

=> X = (ribbon is 25m long)/(width of ribbon is 10.5 cm )

[ from ( 1 )]

=> X = 2500/10.5

=> X = (2500 × 10)/(10.5×10)

=> X = 25000/105

=> X = 5000/21

=> X = 238.0952381

approximately we can write it as

=> X = 238

Hence, raju can make 238 bookmarks from 25 m ribbon.

i hope it helps you.
