1. We used the term “unit fraction” in our problem at the beginning of class and in the reading we did today. In your own words, explain what a unit fraction is and provide an example. 2. What surprised you most about the history of fractions?

3. If you were given another opportunity to explore some historical aspect of mathematics, can you think of a topic that might interest you?

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

answer: it's d

step-by-step explanation:

2/3

step-by-step explanation:

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.
