At the grocery store, 1 pound of grapes cost $3.50. At this rate, how much would 3 pounds cost?

10.5

Step-by-step explanation:

3.50 x 3

10.50

Step-by-step explanation:

We can use a ratio to solve

1 lb          3 lbs

=

3.50        x dollars

Using cross products

1*x = 3*3.50

x =10.50

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
