In a school, 135 students out of 900 are in the 6th grade. Out of every 100 students, how many students are 6th grade students?

Out of every 100 students there are 15 6th grade students.

Step-by-step explanation:

The original number is changed and divided by nine, the original number being 900. In the question, it has been divided by 9.

Since 900 is divided by 9, 135 has to be divided by 9.

135/9=15

Hope this helps.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
