How to reduce (simplify) ordinary fraction 8/21? Fraction can't be reduced (simplified). 8/21 = 0.380952380952; Result written as a positive proper fraction and a decimal number. Ordinary (simple, common) math fraction reducing to lowest terms (simplifying), answer with explanations below
Solve the following system using substitution:
{y + 2.3 = 0.45 x
{-2 y = -3.6
In the second equation, look to solve for y:
{y + 2.3 = 0.45 x
{-2 y = -3.6
-3.6 = -18/5:
-2 y = -18/5
Divide both sides by -2:
{y + 2.3 = 0.45 x
{y = 9/5
Substitute y = 9/5 into the first equation:
{4.1 = 0.45 x
{y = 9/5
In the first equation, look to solve for x:
{4.1 = 0.45 x
{y = 9/5
4.1 = 41/10 and 0.45 x = (9 x)/20:
41/10 = (9 x)/20
41/10 = (9 x)/20 is equivalent to (9 x)/20 = 41/10:
{(9 x)/20 = 41/10
{y = 9/5
Multiply both sides by 20/9:
Answer: {x = 82/9
{y = 9/5
300 because
You have to multiply 81 times 100 and then divide by 27

Step-by-step explanation:
5
.75 pounds in each bag. If you add the total pounds of meat in the 2 packages, 4.5+2.25 you get 6.75. if you divide all 6.75 pounds equally into 9 bags, 6.75/9, you would get a total of .75 or 3/4 of a pound in each bag.
