Answer 1

ANSWER:

1. Number of students = 76

Number of teachers = 4

The ratio of the number of teachers to the number of students =

$\frac{76}{4}$ = $\frac{19}{1}$

So, the ratio of the number of teachers to the number of students = 19:1

This means that there is 1 teacher present for every 19 students

2. Total number of students = 25

Number of boys = 10

Number of girls = Total number of students - Number of boys

Number of girls = 25 - 10

Number of girls = 15

The ratio of the number of boys to the number of girls =

$\frac{10}{15}$ = $\frac{2}{3}$

So, the ratio of the number of boys to the number of girls = 2:3

3. 1kg = 1000 grams

Weight of ceiling fan = 3kg = (3 x 1000) grams = 3000 gms

Weight of handmade fan = 100 gms

The ratio of the weight of the ceiling fan to the hand made fan =

$\frac{3000}{100}$ = $\frac{30}{1}$

So, the ratio of the weight of the ceiling fan to the hand made fan = 30:1
