Susan was supposed to use 5/4 of a cup of butter in her recipe, but she only used 3/4 of a cup of butter.

a. What fraction of the butter that she should

have used did Susan actually use? Make a

math drawing to help you solve this problem

and explain your solution.

b. Describe the different unit amounts that occur

in part (a). Discuss how one amount can be de-

scribed with two different fractions depending

on what the unit amount is taken to be.

Step-by-step explanation:

We can see the fractions and of cups.

It can be seen that denominator has 4 i.e. the fraction .

Let us suppose, a unit is equal to of a cup.

Susan was supposed to use of a cup.

i.e. 5 units of butter was to be used.

But, actual recipe has only 3 units of butter.

a.

Alternatively, we could have directly divided the given fractions:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
