Question

what is 9/15 as a rational number

Answer 1

Answer:

Perimeter of

a square =40m Perimeter of rectangle =

5

2

of $$40-2=16-2=14

−15

9

(i) denominator

5 , then

−15+(−3)

9÷(−3)

=

5

−3

−15

9

(i) denominator

5 , then

−15+(−3)

9÷(−3)

=

5

−3

(ii)

numerator −12, then

5×4

−3×4

=

20

−12

(iii)

denominator 30, then

5×6

−3×6

=

30

−18

(ii)

numerator −12, then

5×4

−3×4

=

20

−12

(iii)

denominator 30, then

5×6

−3×6

=

30

−18

∴

Length + Breadth =

2

Perimeter

=

2

14

=7m

If length is

1 , then breadth =

3

1

l+b=1+

Now divide 7m in the ratio of 1:

3

1

⇒3:1

∴

Length =

3+1
