Question

Robert surveyed 300 of the students in his school about their favorite color. 70% said their favorite color was blue. How many students' favorite color was blue?

Answer 1

Answer:

210

Step-by-step explanation:

We can get 10% of 300 by doing 300 / 10 which is 30. 70 / 10 is 7, so we need 7 lots of 10% to work out 70%. Therefore, 30 * 7 students said that their favourite colour was blue, which is 210.

Answer 2

Answer:

210

Step-by-step explanation:

So 70% OF 300 students said their favorite color was blue

OF means multiply and 70% is equal to .70 so,

.70 x 300 = the number of students that said their favorite color was blue

                =210

So, the number of students that said their favorite color was blue is 210 students. :)
