100 / 7.45 = 13.422818791... (7.45 x that number = 100)
13.422818791... x 5.51 = 73.9597315436... (makes 5.51 equal to 7.45, if you know what I mean)
100 - 73.9597315436 = 26.040268456...% (difference between 100(7.45) and 73.95...(5.51)) 
Answer - 26.040268456%
This is my answer. I THINK it is correct but I do not guarantee it. enjoy!

Answer:
tekilochka [14]

Answer:

Grapes 12 lbs

Apples 20 lbs

Oranges 6 lbs

Cantaloupe 15 lbs

Peaches 15 lbs.

Step-by-step explanation:

Sammy has bought 12 lbs of Grapes.

Now, weight ration of Apples to Grapes is 5 : 3

Therefore, he bought Apples of \frac{12 \times 5}{3} =20 lbs

The wight ration of Grapes to Oranges is 4 : 2

Therefore, he bought Oranges of \frac{12 \times 2}{4} =6 lbs

Again, the weight ratio of Cantaloupe to Apples is 3 : 4

Therefore, he bought Cantaloupe of \frac{20 \times 3}{4} =15 lbs

Finally the weight ratio of Oranges to Peaches is 2 : 5

Therefore, he bought Peaches of \frac{6 \times 5}{2} =15 lbs

<u>Solution-</u>

1.

Bill bought a computer and a printer for a total of $650.

Let p stand for the cost of the printer, so

\text{Cost of the computer + p} =650

\Rightarrow 525+p=650

\Rightarrow p=650-525=125

2.

Bonnie ordered 27 products from one company

Let m stand for the number of missing items

\text{Number of item she got + m} =27

\Rightarrow 19+m=27

\Rightarrow m=27-19=8

3.

Terri bought four lipsticks for a total cost of $20

Let l stand for the cost of one lipstick.

Price\ of\ one\ lipstick \times I=20

\Rightarrow 4 \times I=20

\Rightarrow I=5

Let h stand for the number of hours

Tota\l time\ taken\ = Time\ taken\ for\ 1\ survey\ in\ hours\times no.\ of\ survey

5.

Andy played golf three times during his vacation. His scores were 92, 87, and 88.
