Answer:

It will decrease by 6 3/10 lbs in the 3 1/2 hours

Step-by-step explanation:

The rate is -1 4/5 lbs per hour

The time is 3 1/2 hours

Multiply to find the weight change

-1 4/5 * 3 1/2

Change to improper fractions

- ( 5*1 +4) /5 * ( 2* 3+1)/2

- 9/5 * 7/2

-63/10

Changing back to a mixed number

-6 3/10

It will decrease by 6 3/10 lbs in the 3 1/2 hours
