Answer:
16 portions.
Step-by-step explanation:
John has amount of dog food = 12 pounds
He wants to separate this food for his dogs weighing each portion = [tex]\frac{3}{4}[/tex] pounds
Let x be the number of portions of dog food.
Then amount of dog food = [tex]\frac{3x}{4}[/tex] pounds
Now we plug in the values in the equation
12 = [tex]\frac{3x}{4}[/tex]
x = [tex]\frac{4\times 12}{3}[/tex]
= [tex]\frac{48}{3}[/tex]
= 16 portions
There will be 16 portions of the dog food weighing [tex]\frac{3}{4}[/tex] pounds each.
