Answer:

13/8 = 1 5/8

Step-by-step explanation:

first make 3 1/4 into an improper fraction

3 1/4 = (3*4+1)/4 = 13/4

13/4 /2

we know that dividing by a number is multiplying by its reciprocal, so

(13/4)/2 = 13/4 * (1/2)

multiply the numerators together, and multiply the denominators together

13/4 * (1/2) = (13*1)/(4*2) = 13/8 = 1 5/8

Answer:

b. 61.75

Step-by-step explanation:

Split it into a rectangle and a triangle

1. Rectangle

You can see that the side lengths are 7 and 6.5, so the area is 7 * 6.5 = 45.5

2. Triangle

You know that the base is 6.5 and that the height is 5 (because 12 - 7 = 5) so you can find the area by doing 6.5 * 5 / 2 = 16.25

3. Total

Add the two areas, so 45.5 + 16.25 = 61.75

Answer:

$\boxed{\sf{14}}$

Step-by-step explanation:

$\boxed{\underline{\text{ORDER OF OPERATIONS:}}}$

Use the order of operations.

Note: PEMDAS or BODMAS stands for:

PEMDAS

Parentheses
Exponents
Multiply
Divide
Add
Subtract

BODMAS

Brackets
Order
Divide
Add
Subtract

First, do parentheses.

3+6*(5+4)÷3-7

(5+4)=9

$\Longrightarrow: \sf{3+6* 9\div 3-7}$

Do multiply and divide.

6*9=54

54/3=18

Then, rewrite the problem down.

$\Longrightarrow: \sf{3+18-7}$

Add.

$\sf{3+18=21}$

$\sf{21-7=\boxed{\sf{14}}$

$\Longrightarrow: \boxed{\sf{14}}$

Therefore, the correct answer is "C. 14".

I hope this helps, let me know if you have any questions.

Answer:

(C) Victoria has six sevenths of a pizza. She ate one fourth of it for dinner. How much pizza did Victoria eat for dinner?

Step-by-step explanation:

One clue is "of" in the story and which matches "times" in the equation sentence. The question is is about multiplication.

Words such as "more" "and" & "total" are usually clues that the question is about addition. "Give" "take" "difference" & "have/are left" are clues that there is subtraction in the process. (Please give brainliest!!)

What is ⅓ divided by ¼? Use the model if needed. Answer should be in simplest form. Explain your answer

Misha Larkins [42]

Answer:

The answer to the expression in simplest form is:

$\frac{\frac{1}{3}}{\frac{1}{4}}=\frac{4}{3}$

Step-by-step explanation:

Given the function

$\frac{\frac{1}{3}}{\frac{1}{4}}$

solving to get the simplest form

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}$

$\frac{\frac{1}{3}}{\frac{1}{4}}=\frac{1\cdot \:4}{3\cdot \:1}$

$\mathrm{Apply\:rule}\:a\cdot 1=a$

$=\frac{4}{3}$

Thus, the answer to the expression in simplest form is:

$\frac{\frac{1}{3}}{\frac{1}{4}}=\frac{4}{3}$
