The first thing you want to do is get them all into decimal format. You can do this to fractions by dividing the denominator from the numerator. then you organize the decimals into least to greatest.

0.25; 0.479; 0.5; 0.5625

0.25; 23/48; 0.5; 9/16

Hope it helped.

Answer:

$\boxed {\boxed {\sf Haircut: \$47 \ and \ Color: \$ 100}}$

Step-by-step explanation:

Let's set up a system of equations. (1 equation for yesterday and 1 for today).

Let h = haircut and c= color

$2h+1c= 194$ (Yesterday: 2 haircuts and 1 color for $194).

$2h+4c= 494$ (Today: 2 haircuts and 4 colors for $494).

Notice that both equations have a 2h. If we subtract the two equations, the 2h will cancel and leave us with one variable, c.

$\ \ (2h+1c=194) \\- (2h+4c=494)$

$\ \ 1c=194 \\- (4c=494)$

$-3c= -300$

Since we are solving for c, we must isolate the variable. It is being multiplied by -3. The inverse of multiplication is division. Divide both sides by -3.

$-3c/-3=-300/-3 \\c= -300/-3 \\c=100$
