Answer 2

Answer 1 :-

• There are 112 turtles and frogs in the pond.

Given :-

• In a pond, there are 89 frogs and 23 turtles.

To find :-

• The total number of frogs and turtles in the pond.

Step-by-step explanation :-

There are 89 frogs and 23 turtles in the pond. So, to find the total number of frogs and turtles, we have to add 89 and 23.

89 + 23 = 112.

Thus, the total number of frogs and turtles in the pond is 112.

Answer 2 :-

• Ankur has more pencils.
• He has 12 more pencils than Sneha.

Given :-

• Ankur has 60 pencils.
• Sneha has 48 pencils.

To find :-

• The person who has more pencils and by how much.

Step-by-step explanation :-

In this question, it has been given that Ankur has 60 pencils and Sneha has 48 pencils. We know that 60 is greater than 48, so that means Ankur has more pencils. Now, to find out by how much Ankur has more pencils, we have to find the difference between Ankur and Sneha's pencils. For this, we will subtract 48 from 60.

60 - 48 = 12 pencils.

Thus, Ankur has more pencils and he has 12 more pencils than Sneha.

Answer 3 :-

• The cost of 9 such toy cars is Rs 648.

Given :-

• The cost of a toy car is Rs 72.

To find :-

• The cost of 9 such toy cars.

Step-by-step explanation :-

In this question, it has been given that the cost of 1 toy car is Rs 72. We have to find the cost of 9 such toy cars. For this, we will multiply the cost of 1 toy car by 9, since we have to find the cost of 9 toy cars. That means we have to multiply 72 by 9.

72 × 9 = 648.

So, the cost of 9 such toy cars is Rs 648.

Answer 4 :-

• The cost of 1 such chocolate is Rs 6.

Given -:

• 5 chocolates cost Rs 30.

To find :-

• The cost of 1 chocolate.

Step-by-step explanation :-

In this question, it has been given that the cost of 5 chocolates is Rs 30. We have to find the cost of 1 such chocolate. For this, we will divide the cost of 5 chocolates by 5. That means we have to multiply 30 by 5.

$\sf \dfrac{30}{5} = 6.$

So, the cost of 1 such chocolate is Rs 6.
