Question

Of the 650 students at Harrison Middle School, 40% made the honor roll last semester. How many students made the honor roll last semester?

A.
520
B.
260
C.
16
D.
610

Answer 1

B. 260

I. 650 x 0.4 = 260

Ii. 650 ÷ 100 × 40 = 260

III. in my head I usually find percentage answers quickly by working in 10% increments. Move the decimal one place to the left, giving 65 (10%) and then multiply 65 by 4 (or 70 x 4, take 20- if you find the nearest ten easier).

Answer 2

B 260

Explanation:

650 x 0.4 = 260
