Question

Arrange the following ratio in the ascending order of magnitude: 2:5,3:7,1:3​

Answer 1

Answer:

we have,

2:5=2/5

3:7=3/7

1:3= 1/3

Step-by-step explanation:

Now,

L.C.M of 5,7 and 3= 105

so,

2/5= 42/105

3/7= 45/105

1/3 = 35/105

Therefore,

35 < 42 < 45

• 35/105 < 42/105 < 45/105

• 1/3 < 2/5 < 3/7

• 1:3 < 2:5 < 3:7

Hence, 1:3 < 2:5 < 3:7 ANS.....

Answer 2

Answer:

It is given that

2:3,17:21,11:14 and 5:7

We can write it in fractions as

2/3,17/21,11/14,5/7

Here the LCM of 3, 21, 14 and 7 is 42

By converting the ratio as equivalent

2/3=(2×14)/(3×14)=28/42

17/21=(17×2)/(21×2)=34/42

11/14=(11×3)/(14×3)=33/42

5/7=(5×6)/(7×6)=30/42

Now writing it in ascending order

28/42,30/42,33/42,34/42

By further simplification

2/3,5/7,11/14,17/21

So we get

2:3,5:7,11:14and17:21
