If: 5/6r = 2/3 then r = 5/4 or 1.25

21 4t2+6r-tr 4[-3]2+6[5]-[-3][5] 8[-3]+30-[-15] -24+30+15=21

2 over 3 equals 8 over 12

6r * 5r^2 = 30r^3 ------------ multiply the bases and add the exponents ( 6r is really 6r^1, but the implied 1 is never written as mathematical convention )

It equals 3 over 6 which equals 1 over 2. Your welcome.

3+10-r+6r = -3+9r+0 13+5r = -3+9r 16 = 4r r = 4

-6r + 1 = -17, then (17+1)=18=6r, so r=(18/6)=3. The answer is r=3

2/5 divided by 3/10 equals .4/.3 which equals 4/3 or 1.33333333

2 over 3 plus four over six equals 2

1/2 3 over 4 is 0.75 x 2 over 3 equals 0.5 or 1/2

12 - 6r = 2r + 36 Add 6r to each side: 12 = 8r + 36 Subtract 36 from each side: -24 = 8r Divide each side by 8: r = -3

It is: 1/3 plus 1/3 = 2/3

2 over 3 can not be simplified 2 over 3 minus 1 over 6 equals one-half

The calculation of 2 over 3 equals the decimal 0.66.., and the calculation of 1 over 6 equals 0.16...

3/2 minus 2 equals -1/2

3 divided by -2/3 equals -4.5

2/9+4/9=6/9, which equals 2/3

2/3 equals 20/30 7/10 equals 21/30 2/3 is less than 7/10.

Divide both sides by 6: 3 - r = 0, so r = 3 satisfies the equation.

No! 24 over 36 equals 2 over 3.

c = -2.75 or -2 and 3/4

1/3 + 2/5 = 11/15

2/3 is equivalent to 66.6 recurring / 100 (that is, 66.6666.../100).

2 over 3 plus 5 over 9 equals 11 over 9 or 1 and 2 ninths.

If: 6x = 2/3 Then: x = 1/9

No it does not it equals 3 over 5.
