Start by finding the dimensions of the second picture.
About 4.5 inches by 6.75 inches
We are given that Kelly cuts one picture that is 4 inches by 6 inches. She wants the next picture to be 75 % as large as the first picture and the third picture to be 150 % as large as the second picture. We want to find the approximate dimensions of the third picture.
Let's start by finding the dimensions of the second picture. Recall that this picture is 75 % as large as the first picture. Therefore, to obtain its dimensions, we will multiply the dimensions of the first picture by 75 %.
Now we can calculate the dimensions of the second picture.
| Width | Length |
|---|---|
| 4* 75 % | 6* 75 % |
| 4 * 75/100 | 6 * 75/100 |
| 300/100 | 450/100 |
| 3 | 4.5 |
The second picture is 3 inches by 4.5 inches. Finally, we can find the dimensions of the third picture using the fact that it is 150 % as large as the second picture. To do so, we will multiply the dimensions of the second picture by 150 %.
Let's calculate the dimensions of the third picture.
| Width | Length |
|---|---|
| 3* 150 % | 4.5* 150 % |
| 3 * 150/100 | 4.5 * 150/100 |
| 450/100 | 675/100 |
| 4.5 | 6.75 |
The third picture is 4.5 inches by 6.75 inches.
