To find out how many pints of white paint Sarah used to paint her bedroom walls, we need to subtract the amount of blue paint from the total amount of paint used.
Given that Sarah used 6.8 pints of blue and white paint combined, and 3/4 of this amount is blue paint, we can calculate the amount of white paint used.
Let's set up an equation:
Total paint used = Blue paint + White paint
6.8 pints = 3/4 * 6.8 pints (blue paint) + White paint
To find the amount of white paint, we need to subtract the amount of blue paint from the total paint used.
White paint = Total paint used - Blue paint
White paint = 6.8 pints - 3/4 * 6.8 pints
White paint = 6.8 pints - 5.1 pints
White paint = 1.7 pints
Therefore, Sarah used 1.7 pints of white paint to paint her bedroom walls.
To find out how many pints of white paint Sarah used, we'll need to subtract the amount of blue paint from the total amount of paint used.
First, let's determine the total amount of paint used. According to the information given, Sarah used 6.8 pints of blue paint and white paint in total.
Next, we need to find out how much of this total amount is blue paint. According to the problem, 3/4 of the total amount is blue paint. We can find this by multiplying the total amount by 3/4:
6.8 * (3/4) = 20.4/4 = 5.1 pints of blue paint
Now, we can calculate the amount of white paint Sarah used by subtracting the blue paint from the total amount:
Total amount - Amount of blue paint = Amount of white paint
6.8 - 5.1 = 1.7 pints of white paint
Therefore, Sarah used 1.7 pints of white paint to paint her bedroom walls.
try typing fractions so they make sense, as in 3/4
3/4 blue, so 1/4 white
1/4 * 34/5 = 34/20 = 17/10
or
0.25 * 6.8 = 1.7
