Answer:
a. b. c. and d. are true; e. is false
Step-by-step explanation:
1 gallon of red paint : 3 gallons of yellow paint
&
1 gallon of red paint + 3 gallons of yellow paint = 4 gallons of orange paint
<em>a. 3/4 of a 4-gallon mix would be yellow paint.</em>
<em>True. 3 out of 4 gallon mix is yellow and 1 out 4 is red</em>
<em />
<em>b. Every 1 gallon of yellow paint requires 1/3 gallon of red paint.</em>
1 gallon of red paint : 3 gallons of yellow paint
divide by 3 in both sides of :
1/3 gallon of red paint : 3/3 gallons of yellow paint
<em>1/3 gallon of red paint: 1 gallon of yellow paint. True</em>
<em />
<em>c. Every 1 gallon of red paint requires 3 gallons of yellow paint.</em>
<em>True. </em>1 gallon of red paint : 3 gallons of yellow paint
<em />
<em>d. There is 1 gallon of red paint in a 4-gallon mix of orange paint.</em>
<em>True. 1 out of 4 is red and 3 out of 4 is yellow.</em>
<em />
<em>e. There are 2 gallons of yellow paint in an 8-gallon mix of orange paint.</em>
<em />
1 gallon of red paint + 3 gallons of yellow paint = 4 gallons of orange paint
Multiply by 2 each side of the equation
2(1 of red paint + 3 of yellow paint) = 2(4 of orange paint)
apply to each member of the parenthesis ()
2 of red paint + 6 of yellow paint = 8 of orange paint
Actually there are 6 gallons of yellow paint in a 8 gallon mix. So e. is false.
