Question

1) 90÷х=45÷5 2) 36÷y=40÷10

Answer 1

$90 \div x = 45 \div5 \\ 90 \div x = 9 \\ x = 90 \div 9 \\ x = 10 \\ \\ 36 \div y = 40 \div 10 \\ 36 \div y = 4 \\ y = 36 \div 4 \\ x = 9$

Answer 2

№ 1.

Решение.

90 : x = 45 : 5

90 : x = 9

x = 90 : 9

x = 10

Ответ: x = 10

№ 2.

Решение.

36 : у = 40 : 10

36 : у = 4

у = 36 : 4

у = 9

Ответ: у = 9

Answer 3

To solve the equations, we need to find the values of 'x' and 'y' that satisfy the equations. Let's solve them step-by-step:

1. 90÷х = 45÷5

To find the value of 'x', we need to isolate it on one side of the equation. First, let's simplify the right side of the equation:

45 ÷ 5 = 9

Now the equation becomes:

90 ÷ x = 9

To find the value of 'x', we can cross-multiply:

90 * 1 = 9 * x

Simplifying further:

90 = 9x

Now, divide both sides by 9 to isolate 'x':

x = 90 ÷ 9 x = 10

So, the value of 'x' is 10.

2. 36÷y = 40÷10

Let's simplify the right side first:

40 ÷ 10 = 4

Now the equation becomes:

36 ÷ y = 4

To find the value of 'y', we'll perform similar steps as before. Cross-multiply:

36 * 1 = 4 * y

Simplifying further:

36 = 4y

Now, divide both sides by 4 to isolate 'y':

y = 36 ÷ 4 y = 9

So, the value of 'y' is 9.

Therefore, the solutions to the equations are:

1. x = 10
2. y = 9
