How do i add and subtract fractions? that would help me a lot

Check to see if the denominators of the fractions are the same. Convert them to identical fractions of the same denominator if they don't have the same denominator. Add or remove the numbers in the numerator until they have the same denominator. Put the new numerator over the denominator in your answer.

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'.
