Answer 2

90÷X=30

X=90÷30

X=3

Пр.90÷3=30

30=30

X÷8=100

X=100×8

X=800

Пр.800÷8=100

100=100

X÷4=16

X=16×4

X=64

Пр.64÷4=16

16=16

27÷X=3

X=27÷3

X=9

Пр.27÷9=3

3=3

Answer 3

To solve these equations, let's solve them one by one:

1. 90/???? = 30

To solve for ????, we can multiply both sides of the equation by ????/30:

(90/????) * (????/30) = 30 * (????/30)

Canceling out ????/30 on the right side, we get:

90 = ????

So, ???? = 90.

2. ????/8 = 100

To solve for ????, we can multiply both sides of the equation by 8:

(????/8) * 8 = 100 * 8

Canceling out 8 on the left side, we get:

???? = 800

So, ???? = 800.

3. ????/4 = 16

To solve for ????, we can multiply both sides of the equation by 4:

(????/4) * 4 = 16 * 4

Canceling out 4 on the left side, we get:

???? = 64

So, ???? = 64.

4. 27/???? = 3

To solve for ????, we can multiply both sides of the equation by ????/3:

(27/????) * (????/3) = 3 * (????/3)

Canceling out ????/3 on the right side, we get:

27 = ????

So, ???? = 27.

In summary, the solutions to the equations are:

???? = 90 ???? = 800 ???? = 64 ???? = 27
