A sheet of paper is 5 cm x 12 cm. Ravi has to draw a margin of width 1 cm along one

4 3length and of width cm along the other three sides. Find the measurements of the

5 paper left for him to write on.

Step-by-step explanation:

We first need to decide where we want the 1 and 1/4 to come off of.

Here we will prove that it is on the 12cm side

the 5 & 12 measurements will have 2 values reduced from them.

One side will have double 3/5's removed and the other will have one 3/5 and the 1_1/4.

The 12 side: 12 - 3/5 - 1_1/4 we turn them all into fractions/improper fractions

(common denominator of 5 and 4 is... 20..... and 1_1/4 = 5/4)

240/20 - 12/20 - 25/20 = (240-12-25) / 20 = 203 / 20

203 / 20 = 10_3/20

The 5 side: will have double 3/5's removed

5 - 3/5 - 3/5 ..... ( the common denominator will be 5)

25/5 - 3/5 - 3/5 = (25-3-3) / 5 = 19/5

19/5 = 3_4/5

The dimensions are then 10_3/20 cm by 3_4/5 cm
