Use the givem advertisement to determine the missing part in each ratio. write the two unit rates.

yogurt
4 packs/$5.00

=4 yogurts/$5.00=1 yogurt/?=?/$1.00

5.00 / 4 = $1.25

1.25=2.50

To find the missing part in each ratio, we can use the given advertisement:

yogurt:
4 packs/$5.00

To fill in the missing part of the first ratio, we need to determine how many yogurts are in 1 pack. Since there are 4 packs in $5.00, we can divide $5.00 by 4 to find out the cost of 1 pack of yogurt:

$5.00 ÷ 4 packs = $1.25/pack

Now we can fill in the first ratio:

= 4 yogurts/$5.00 = 1 yogurt/$1.25

Next, to find the missing part in the second ratio, we want to determine how many yogurts we can get for $1.00. Since we know that 1 pack costs $1.25, we can divide $1.00 by $1.25 to figure out how many yogurts we can get for $1.00:

$1.00 ÷ $1.25/pack = 0.8 packs

Since we cannot have a fraction of a pack, we can't write 0.8 packs as the missing part. Instead, we'll convert 0.8 packs into a whole number by multiplying it by the number of yogurts in 1 pack (which is 4):

0.8 packs × 4 yogurts/pack = 3.2 yogurts

Therefore, the missing part of the second ratio is 3.2 yogurts. Now we can fill in the second ratio:

= 1 yogurt/$1.25 = 3.2 yogurts/$1.00

To summarize, the two unit rates are:
- 1 yogurt/$1.25
- 3.2 yogurts/$1.00
