Answer:

It removes the repeating part of the decimal from the equation.

Step-by-step explanation:

Described here is the process of converting the repeating decimal fraction into fraction in the form of p/q

1) --------------

x = 0.555555

2) --------------

10x = 5.555555

3) --------------

10 x - x = 5.555555 - 0.555555
9x = 5
x = 5/9

So the purpose of step 3 here is to remove the repeating part of the decimal from the equation

Correct option is the first one.

Sally used all of the paint shown to make a certain tint of orange paint. How many pints of red paint should be mixed with 24 pi

ruslelena [56]

Answer:

18 pints

Step-by-step explanation:

As we can see, three pint of yellow paint was mixed with four pint of red paint. Let x represent the number of yellow paint and let y represent the number of red paint. Therefore, the ratio of the two paints is:

x/y = 3/4

x = (3/4)y

To calculate the number of red paints (x) that is needed to be mixed with 24 pints of yellow paint, we use the equation and substitute y as 24. Hence:

x = (3/4)y

x = (3/4) * 24

x = 18 pints
