A sheet of paper is 5 cm x 12 cm. Ravi has to draw a margin of width 1 and 1/4 cm along one
length and of width 3/5 cm along the other three sides. Find the measurements of the paper left for him to write on.

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
Step-by-step explanation:
you will first need to decide where you want the 1 and 1/4 to come off of.
I will show you if it's off the 12cm side
both the 5 & 12 measurements will have 2 values subtracted from them.
One 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 .... 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 ..... (common denom is 5)
25/5 - 3/5 - 3/5 = (25-3-3) / 5 = 19/5
19/5 = 3_4/5
Dimensions are then 10_3/20 cm by 3_4/5 cm
If you cut off the margins with the 1_1/4 off the 5cm side, the dimensions will be much different
