Find three rational numbers between 1 and 0.​

1/2, 1/4 & 3/4

Step-by-step explanation:

mean of 0 &1 is

mean of 0 and 1/2 is

mean of 1/2 and 1 is

So the three rational numbers are 1/2, 1/4 & 3/4

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
