Question

Shobha's exam marks were: Maths 21/25 English 11/15 , Hindi 18/20.
Change the results into percentages and arrangethem in ascending order.

Answer 1

Step-by-step explanation:

maths = 84 percent

English = 73.9 percent

hindi = 90 percent

73.9, 84 , 90

Answer 2

Given :–

Results of 3 subjects,

• Maths = $\dfrac{21}{25}$
• English = $\dfrac{11}{15}$
• Hindi = $\dfrac{18}{20}$

To Find :–

1. Change the results into percentages.
2. Arrange the results in ascending order.

Solution :–

1. First, we need to convert the given results into percentages.

For converting the percentages, we need to multiply 100 by the given result.

So,

• Maths = $\dfrac{21}{25}$

⟹ $\dfrac{21}{\cancel{25}} \times \cancel{100}$

Cancel 25 and 100 by 25, we get 4.

⟹ 21 × 4

⟹ 84%

• English = $\dfrac{11}{15}$

⟹ $\dfrac{11}{\cancel{15}} \times \cancel{100}$

Cancel 15 and 100 by 5, we obtain

⟹ $\dfrac{11}{3} \times 20$

Now, multiply the denominator by 20, we obtain

⟹ $\dfrac{220}{3}$

Now, divide the denominator and the numerator, we obtain

⟹ 73.33%

• Hindi = $\dfrac{18}{20}$

⟹ $\dfrac{18}{2\cancel0} \times 10\cancel0$

Cancel the both zeors.

⟹ $\dfrac{18}{\cancel2} \times \cancel{10}$

Cut 2 and 10 by 2, we get 5.

⟹ 18 × 5

⟹ 90%

Hence,

The results in percentages are:

• Maths = 84%
• English = 73.33%
• Hindi = 90%

2. Now, we need to arrange the results in ascending order.

So,

Ascending order – Arranged the numbers from smallest to largest.

So,

Ascending order of the results is:

In subjects name:

⟹ English, Maths, Hindi

In percentages:

⟹ 73.33%, 84%, 90%

In factions:

⟹ $\dfrac{11}{15}$, $\dfrac{21}{25}$, $\dfrac{18}{20}$
