Question

60% of the total students in a school are girls. If there are 800 boys in the
school, find the number of girls.
​

Answer 1

please mark me as brainliest plsssss

60% : 800 ÷ 100 = 8 (1 %)

8 × 60 =480 (60 %)

So 480 students are girls, the rest of the students should be a boy.

800 — 480 = 320

320 student are boys. (aka 40 %)

You can also calculate what 40 % is, because 60% is girls out of 100%

100% - 60% = 40% (is a boy)

So 800 ÷ 100 = 8 (1%)

8 × 40 = 320

Answer 2

Answer:

1200

Step-by-step explanation:

if 40% =800

20% = 400

then 10%= 200

200 × 6= no of girls
