Ответ:
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 =
pounds
Let x be the number of portions of dog food.
Then amount of dog food =
pounds
Now we plug in the values in the equation
12 =![\frac{3x}{4}](/tpl/images/0164/2627/c861e.png)
x =![\frac{4\times 12}{3}](/tpl/images/0164/2627/c82b2.png)
=![\frac{48}{3}](/tpl/images/0164/2627/99727.png)
= 16 portions
There will be 16 portions of the dog food weighing
pounds each.
