Equivalent Ratio

The different ratio can be compared with each other to know whether they are equivalent or they are not equivalent. To check whether they are equivalent, first,  we write the ratio in the fraction form and then convert them in like fractions.

Example: 1:2 is equal to 2:3?

Solution: 1/2*3/3            =3/6

2/3*3/3=4/6

3/6<4/6.

1/2<2/3

The ratio 1:2 is not equivalent to the ratio 2:3

Keeping things in proportion and getting solutions.

We have studied unitary method in earlier classes. In this method, we find the value of one unit and then we find the value for the required numbers.

Example:  6 chocolates cost Rs 180. Find the cost of 2 chocolates?

Solution: 6 Chocolates=180

1 chocolate=180/6

1 chocolate=Rs 30

2 Chocolates=30*2=60

Hence, we can say that 2 chocolates cost Rs 60 only.
