For the addition problem 1/4 would turn into 2/8 and the 3/8 would stay the same therefore it would be 2/8 + 3/8 =5/8. Then for the subtraction problem 1/4 would turn into 2/8 and 3/8 would stay the same therefore it would be 2/8 - 3/8 =1/8
        
             
        
        
        
Answer:
Direct Variation
Step-by-step explanation:
The relationship between two variables such that y = kx if k is a nonzero number. Also, as one quantity increases, the second quantity increases or as one quantity decreases, the second quantity decreases. Therefore ac=5 is a direct variation
 
        
             
        
        
        
Answer:
Angle L is a base angle and measures 72°.
Step-by-step explanation:
Triangle JKL is isosceles.
The measure of angle J is 72°
The measure of angle K is 36°
Angles in a trinagle add up to 180° so angle L is;
180° - (36° + 72°) = 72°
An isosceles triangle means that two of its sides are equal and two base angles are equal. So base  angles are angles J and L and measures 72° each.
