Answer:
three sevenths of a cup; [tex]\frac{3}{7}[/tex] of a cup; 0.43 of a cup
Step-by-step explanation:
The ratio of red paint to white paint is 3:7,
You could write this as a fraction too, 3/7.
If there is 1 cup of white paint then that means 3/7 = ?/1
7 divided by 1 equals 7, what you do to the bottom you must do to the top. 3 divided by 7 equals 3/7 of a cup, or 0.43 of a cup.
[tex]\frac{3}{7}[/tex] = [tex]\frac{?}{1}[/tex]
7 ÷ ? = 1
7 ÷ 7 = 1
3 ÷ 7 = [tex]\frac{3}{7}[/tex] or 0.43
[tex]\frac{3}{7}[/tex] = [tex]\frac{0.43}{1}[/tex]
