Question

Steve bought a bag of 2.7 pounds of gummy bears. If she gives 10% of the bag to her friend, how many pounds does she have left?

Answer 1

Answer:

2.43 lbs

Step-by-step explanation:

If she gives away 10%, then she still gets to keep 90% for herself, which means that when comparing it as a ratio to one, she has 0.9/1. You can set up an equation as $\frac{0.9}{1} *\frac{x}{2.7}$. Cross multiply to get x = 2.43. This means that she still has 2.43 pounds of gummy bears for herself after giving away 10%.

Answer 2

We multiply 2.7 by 0.1 first:

2.7*0.1=0.27

Then we subtract that to 2.7:

2.7-0.27=2.43

So Steve will have 2.43 pounds of gummy bears left after he gave 10% to his friend.

I hope this helps!
