Answer: \frac{41}{20}

Step-by-step explanation:

The first step is to make the division of the fractions \frac{9}{16} and

\frac{1}{4}. To do this, you can flip the fraction \frac{1}{4} over and multiply the numerators and the denominators of the fractions. Then:

(\frac{\frac{9}{16}}{\frac{1}{4}})-\frac{1}{5}=(\frac{9}{16}*4)-\frac{1}{5}=\frac{36}{16}-\frac{1}{5}

Reduce the fraction \frac{36}{16}:

 =\frac{9}{4}-\frac{1}{5}

Now you can make the subtraction:  in this case the Least Common Denominator (LCD) will be the multiplication of the denominators.   Divide each denominator by the LCD and multiply this quotient by the corresponding numerator and then subtract the products. Therefore you get:

=\frac{45-4}{20}=\frac{41}{20}

Serga [27]
If its meaning making a profit after the $300 then:
540+300=840
840/24= 33.60
They would charge $33.60 per necklace.

If you were meaning a profit of $540 total then:
540/24=22.5
They would charge $22.50 per necklace.

Minchanka [31]
450/5= 90 units

90/5= 18 units

All you need to do is divide the real dimensions by the scale dimensions, and turn that answer to units. Notice: It said 1 unit: 5 feet

The scale drawing was 90 to 18 units.

I hope this helps!
