There are 60 students in a class. Among them,20 students are girls .Find the ratio ofa. Boys and total studentsb. girls and tota
valina [46]

Answer:

Girls to boys = 1:2

Girls to students = 1:3

Boys to students = 2:3

Step-by-step explanation:

So, let's subtract the number of girls from the number of students in the class:

60 - 20 = 40

This means that for every 20 girls there are 40 boys in the ratio of girls to boys:

20:40

This can be simplified down by factoring, here we can divide by 20:

(20 ÷ 20) : (40 ÷ 20)

1:2

So the ratio of girls to boys is 1:2

The ratio of boys to students can be calculated via:

40:60

This can be simplified by dividing by 20 again:

(40 ÷ 20) : (60 ÷ 20)

2:3

So the ratio of boys to students is 2:3

The ratio of girls to students can be put in a ratio of:

20 : 60

This can be simplified down by dividing by 20:

(20 ÷ 20) : (60 ÷ 20)

1:3

So the ratio of girls to students is 1:3

Hope this helps!

Alisiya [41]

the picture in the attached figure


Applying the Pythagorean Theorem

Find the lengths of the two sidewalks


Step 1

square section

D=√{15²+15²}

D=√450 m

D=21.21 m


Step 2

rectangular section

D=√{15²+8²}

D=√289 m

D=17 m
