Answer 1

Given: Designer has 80 m of cloth, designs a dress in 20m 30 cm of cloth.

To find: How much cloth will be left ?

Solution:

• As the designer has 80 m of cloth, and he designs a cloth of 20m and 30 cm each.

• So first lets convert all the terms from meters to centimeters.

            80m =80 x 100 = 8000 cm

            20m 30 cm = 2000 + 30 cm = 2030 cm

• Now to find how many clothes he can make out of 8000 cm of cloth,

            2030 x 3 = 6090 cm

• The remaining cloth would be:

           8000-6090

           = 1010 cm

Answer:

                   1010 cm  of the cloth will be left. ​
