Rita feeds her dog 2/5 pounds of dog food for each meal Rita has just bought 10 punds of dog food. for how many meals will this food last

25 meals

Step-by-step explanation:

If Rita feeds her dog 2/5 pounds of dog food for each meal, this means;

2/5 pounds = 1 meal

To get the number of meals she will feed if she buys 10 pounds, we will say;

10 pounds = x meals

Divide both equations to get x;

(2/5)/10 = 1/x

Cross multiply;

2/5 x = 10 * 1

2x/5 = 10

2x = 50

x = 50/2

x = 25

Hence the 10pounds food will last 25 meals

4 + 5 7/9= 9 7/9
