Is 8 times 12 divided by 4 = 8 divided by 4 times 12 = 24 the right algorithm? Can multiplication and division exchange positions together?

Is 8 times 12 divided by 4 = 8 divided by 4 times 12 = 24 the right algorithm? Can multiplication and division exchange positions together?

Certainly.

3 / 5 divided by (8-2x) = 0.2 divided by 1 / 2. X = ()

3.25

The solution of X divided by 0.3 - (0.7-0.2x) divided by 0.1 = 1

X divided by 0.3 - (0.7-0.2x) divided by 0.1 = 1 multiplied by 0.3
x-3(0.7-0.2x)=0.3
x-2.1+0.6x=0.3
1.6x=2.1+0.3
1.6x=2.4
x=1.5

What is the quotient of 2.74 divided by 50% of 0.24? 0.3 to 2x equals 1.8 to 7.2

2.74 divided by 50% of 0.24 = 2.74 △ 0.12 = 137 / 6
0.3 to 2x equals 1.8 to 7.2
Then 0.3:2x = 1:4
Then 2x = 1.2
Then x = 0.6
