Step-by-step explanation:

Convert any whole numbers to mixed numbers

$\frac{12}{1} \times \frac{23}{42}$

Use fractions formula

$\frac{a \times b}{c \times d} = \frac{e}{f}$

$\frac{12 \times 23}{1 \times 42} = \frac{276}{42}$

Count how many times 276 goes into 42 evenly

$= 6\frac{4}{7}$

jonny [76]

Answer:

$2\frac{1}{6}\ frames$

Step-by-step explanation:

we know that

To find out how many frames she can make with the exiting material, divide 1 5/8 by 3/4

$1\frac{5}{8}:\frac{3}{4}$

Convert mixed number to an improper fraction

$1\frac{5}{8}=\frac{1*8+5}{8}=\frac{13}{8}$

substitute

$\frac{13}{8}:\frac{3}{4}=\frac{52}{24}\ frames$

Simplify

$\frac{13}{6}\ frames$

Convert to mixed number

$\frac{13}{6}\ frames=\frac{12}{6}+\frac{1}{6}=2\frac{1}{6}\ frames$

Rick buys remote control cars to resell. He applies a markup of 21%. Enter two expressions that represent the retail price of th

11111nata11111 [884]

The two expressions that represent the retail price of cars is: Retail price = 1.21c and Retail price = c + 0.21c

Solution:

Given that,

Rick buys remote control cars to resell

He applies a markup of 21%

Let "c" be the original price of remote control cars

To find: Expression for retail price of car

We know that,

Retail price = original price + markup

Here, markup price = 21 % of original price

Markup price = 21 % of c

Therefore, substituting the given values we get,

Retail price = c + 21 % of c

$\text{ Retail price } = c + 21 \% \times c\\\\\text{ Retail price } = c + \frac{21}{100} \times c\\\\\text{ Retail price } = c + 0.21c\\\\$

This can also be expressed as,

$\text{ Retail price } = c + 0.21c = 1.21c$

Thus two expressions that represent the retail price of cars is: Retail price = 1.21c and Retail price = c + 0.21c
