Answer 1

Answer:

Step-by-step explanation:

Let the number be 4x and 5x.

According to the question,

⇒  

5x+20

4x+20

​

=  

7

6

​

 

⇒28x+140=30x+120

2x=20

x=10

Answer 2

Answer:

The numbers are 40 and 50

Explanation:

Let the numbers are 4x and 5x respectively

Two numbers are in the ratio of 4:5

Each number increased to 5, then the ratio will becomes 9:11

From the question, we have

$\frac{4x+5}{5x+5} = \frac{9}{11} \\44x+55 = 45x+45\\45x-44x = 55-45\\x = 10$

The numbers are

4x = 4*10= 40

5x = 5*10 = 50

The numbers are 40 and 50

Subtraction:

Subtraction is the mathematical function of taking one number out of another. The basic arithmetic function of subtraction, which is denoted by the sign, can be used to determine the difference between two numbers (-). Calculating the difference between two numbers requires the subtraction operation. When you take away a few from an object group, the object group shrinks. For instance, the 9 cupcakes you bought for your birthday party were eaten by your friends—7 of them. Only two cupcakes remain for you. The following can be written as a subtraction equation: "Nine less seven equals two," as the expression goes. 7, when subtracted from 9, yields 2, or (9 - 7)
