Please help me!When two Fractions refer to the same whole and have the same denominators, explain why you can compare only the numerators

Think about it in terms of division

Step-by-step explanation:

if comparing 1/5 with 3/5 both are divided by like terms if you add them you have a total of 4/5 or four parts of a whole, if you were to compare the denominator, you would end up with 4/10. Thinking in terms of a pie for instance: adding 1 slice to your other 3 slices on your plate leaves one slice behind so you took 4 out of the five, the size of the pie doesn't change (the denominator)

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
