It would be .355 gigabytes because 3 gigabytes =3000 megabytes so 3000 minus 2,645 = 355 megabytes and 355 megabytes as gigabytes =.355 gigabytes
Hi there! The answer is 18 pieces.
There are 3 first grade classes and each class has 22 students in it. Therefore there are 3 × 22 = 66 students.
If there are 66 students and each student needs 2 pieces of red paper, there is a total need of 2 × 66 = 132 pieces of red paper.
There are 150 pieces of red paper and there is a total need of 132 of these pieces. Therefore there are 150 - 132 = 18 pieces of red paper left.
The answer is 18 pieces.
~ Hope this helps you!
