# Explain how you can use a quick picture to find 3 times 2.7

Micah spent \$28.1 and Jeremy spent \$34.82.
Sarah needs 3680 inches of ribbon.
All I know is the answer to 3*2.7=8.1.
Julie: \$5.62
Micah: \$28.1 (5.62 x 5 = 28.1)
Jeremy: \$34.82 (28.1 + 6.72 = 34.82)
--
3.68 x 1,000 = 3680
Sarah needs 3680 inches of ribbon
--
3.85 x 4 = 15.4
Adam is carrying 15.4 pounds of books.
If you want to find 3*2.7 with a picture, you could draw 2 rectangles divided into 10 parts shaded in and then the same rectangle with only 7 out of the 10 parts shaded in. Then do the same thing 2 more times. That should help.
Here is an quick example A "quick picture" is an estimate than? 5 x 2.7 5 x 3= 15 Its been a long time since elementary school and I do not remember "quick picture" The question was How can you use a "quick picture" to find 5 x 2.7? the answer is 13.5an estimate would be 15
dose this help?
Draw three rectangles with three rows each and 10 columns in each row. Fill in the first two rows and seven rectangles in each of the large rectangles.
Change it 2.7 * 3 then keep one which is the decimal then multiply 27 * 3 which is 81 we do have the decimal so the answer is 8.1

see the picture 8.1 is answer

5×2.7=13.5
7×2=35, carry the 3.
5×2=10, then add the 3 that was on top and then bring down the final result 13.
Once you've done that you have 135. Your final step is to move the decimal one place to the left which you then get 13.5.
Hope this helped.
3 x 2.7 is the same as 3 x 3 x 0.9 = 9 x 0.9 = 8.1
2 flats 7 long and do it 3 times
