How do you turn a number out of 30 into a number out of 20?
Say you had to turn 9/30 in to twentieths. First you find the common denominator of 30 and 20 (the lowest thing that both of them multiply into) and then multiply the first number into it. So 9/30 would turn into 18/60, which you can then divide by 3 to get twentieths, which is 6/20.
What is the equivalent fraction for 20 over 30?
Oh, what a happy little question! Let's turn that 20 over 30 into a simpler form. We can divide both numbers by 10 to get 2 over 3. Now we have a lovely equivalent fraction that's just as beautiful as a painting of a serene meadow.
12x plus 30 equals 15x-20?
Use algebra. 12x+30=15x-20. Add 20 to both sides. 12x+50=15x. Subtract 12x from both sides. 50=3x. Divide both sides by 3. 16.666...=x
