2. Which is smaller or 2/5 or 3/7?
3. The sides of a triangle are in the ratio 3:4:5. If the perimeter of the triangle is 84cm, then find its sides.
SolutioN :
1.)
Here, If we compare 230/70 with 18/21
we get ,
230/70 = 18/21
23/7 = 6/7
23/7 ≠ 6/7
Hence, The ratios are not same.
2.)
Here, We have to compare 2/5 and 3/7
2/5 = 3/7
0.40 = 0.42
Hence, 0.25 is smaller.
3.)
Let the ratios be 3x, 4x and 5x
As we know that,
Perimeter of triangle = side + side + side
Therefore,
3x + 4x + 5x = 84
12x = 84
x = 84/12
x = 7
Therefore, Sides of triangle are :-
3 * 7 = 21
4 * 7 = 28
5 * 7 = 35
Hence , The sides are 21cm, 28cm, 35cm .
