Question

72% of 25 students are interested in math matics.How many are not interested in mathematics? ​

Answer 1

Answer:

7

Step-by-step explanation:

25/100 = 0.25

0.25*72 = 18

25-18 = 7

Answer 2

Answer:

7 students

Step-by-step explanation:

% = out of 100

72% = 72 parts out of 100 parts

Subtract 100 with 72

100 - 72 = 28

Therefore, 28% of 25 students don't like maths.

The number of students is then determined by using percentage formula

$\frac{xy}{100}=z$

x = the ratio digit, some part out of 100

y = a total of things in a group.

Therefore 28 percent of 25 students has the following equation:

x = 28, y = a total of 25 STUDENTS, so:

$\frac{28*25}{100}$

= 700/100

= 7 students

FINAL ANSWER: Only 7 students who don't like maths.
