guajiro [1.7K]

Answer:

3.25 cm is the answer to 3\frac{1}{4} of a cm.

Step-by-step explanation:

Given:

3\frac{1}{4} of a cm.

Solution:

Type I:

First we will see what is  \frac{1}{4}  

3\frac{1}{4}=0.25

i.e \frac{1}{4}  And  0.25 is SAME.

Now,

3\frac{1}{4}= 3\ and\ 0.25=3+0.25=3.25\ cm

Type II:

3\frac{1}{4}=\frac{4\times 3 + 1}{4}\\3\frac{1}{4}\\=\frac{12+1}{4}\\=\frac{13}{4}\\=3.25\ cm

Ms. Smith purchased ½ of a pound of grapes. She would like to make 112pound portions for this week’s snacks. How many portions w
Elodia [21]

Step-by-step explanation:

There is no enough information to determine how many portions she will be able to make.

We need to know how many pounds of grapes will she needs to make a particular pounds portions for the snacks.

For example, if she needs 2 pounds of grapes to make 5 pounds portion for the snacks, and she purchase ½ pounds of grapes, we can determine how many pounds of portions for the snacks she will be able to make with this information.

Using a simple ratio

2:5 = ½:x

2/5 = ½/x

Multiplying both sides by x

(2/5)x = 1/2

Multiplying both sides by 5/2

x = (1/2)×(5/2)

x = 5/4

x = 1¼ pounds

Meaning she will be able to make 1¼ pounds of portion for snacks with ½ pounds of grapes.
