(iii) Ratio of good mangoes to the rotten mangoes.​

Answer 1

Step-by-step explanation:

1) Ratio of good mangoes to the total mangoes

is -

Good mangoes = Total mangoes - rotten mangoes

= 180 - 30

= 150

Ratio= 180:150

= 36: 30

2) Ratio of rotten mangoes to the total mangoes

= 30:180

=6:36

3)Ratio of good mangoes to the rotten mangoes

=150:30

= 30:6

answers are here.

Answer 2

Your Answer :

Given :

Total no. of mangoes = 180

No. of rotten mangoes = 30

Required to find:

1. Ratio of good mangoes to the total mangoes.
2. Ratio of rotten mangoes to the total mangoes.
3. Ratio of good mangoes to the rotten mangoes.

Solution:

It is given that there are 180 mangoes in a basket in which 30 mangoes are rotten.

So, he asked us to find the ratio of it.

Then, you may be wondering about ratio.

Let me explain about Ratio.

What is Ratio ?

A ratio between two or more quantities is a way of measuring their size compared to each other.

For example : In a class there are 10 boys and 30 girls . What is the ratio of boys is to girls ?

The ratio of boys is to girls is

=> 10 : 30 [ here " is to " becomes ' : ' ]

=> 1 : 3

So , this is meant by Ratio .

In Ratios the first term is known as antecedent .

The second term is known as constant.

Hence, coming to the question

We know only 2 values that is

1. Total No. of mangoes
2. No. of rotten mangoes

Here, we need to find the no. of good mangoes.

So,

No. of good mangoes = Total no. of mangoes - No. of rotten mangoes

Hence,

No. of good mangoes = 180 - 30

= 150

Therefore,

Let's Now solve all the 3 questions

1.

We need to find ratio of good mangoes is to total mangoes ?

Answer :

No. of good mangoes : Total no. of mangoes

=> 150 : 180

=> 15 : 18

=> 5 : 6

2.

We need to find the ratio of rotten mangoes to the total mangoes ?

Answer:

No. of rotten mangoes : Total no. of mangoes

=> 30 : 180

=> 3 : 18

=> 1 : 6

3.

We need to find the ratio of good mangoes to rotten mangoes ?

Answer :

No. of good mangoes : No. of rotten mangoes

=> 150 : 30

=> 15 : 3

=> 5 : 1
