Answer:

$\frac{10}{21}$

Step-by-step explanation:

<u>Operations With Fractions</u>

Evaluate the expression:

$\displaystyle m=\frac{\frac{2}{7}}{\frac{3}{5}}$

The division of fractions is usually done by multiplying the fraction on the numerator by the reciprocal of the fraction on the denominator:

$\displaystyle m=\frac{\frac{2}{7}}{\frac{3}{5}}=\frac{2}{7}\cdot\frac{5}{3}$

Operating:

$\displaystyle m=\frac{\frac{2}{7}}{\frac{3}{5}}=\frac{10}{21}$

This fraction cannot be reduced.

What is the greatest common factor of 16 and 48?

Anna11 [10]

Answer:

Step-by-step explanation:

We can list out each of the numbers' prime factors first before deciding their greatest common factor.

16: 2 × 2 × 2 × 2

48: 2 × 2 × 2 × 2 × 3

As you can see the bolded parts, these are the common factors of the two numbers. To find the greatest common factors, we just have to multiply all their common factors together.

Greatest common factor of 16 & 48: 2 × 2 × 2 × 2 = 16

The cost of 2 jackets and 3 skirts was sh 1800. After the cost of a jacket and that of a skirt was increased by 20%,the cost of

nadya68 [22]

Answer:

New cost of jacket = $1.2x=1.2\times 600=720\ \text{sh}$

New costs of skirt = $1.2y=1.2\times 200=240\ \text{sh}$

Step-by-step explanation:

Let original cost of jacket = $x$

original cost of skirt = $y$

The equation will be

$2x+3y=1800$

New cost of jacket = $1.2x$

New costs of skirt = $1.2y$

The equation will be

$6(1.2x)+2(1.2y)=4800\\\Rightarrow 7.2x+2.4y=4800$

The equations are

$2x+3y=1800$ $\times 0.8$

$7.2x+2.4y=4800$

$1.6x+2.4y=1440$

$7.2x+2.4y=4800$

Subtracting the above two equations we get

$-5.6x=-3360\\\Rightarrow x=\dfrac{3360}{5.6}\\\Rightarrow x=600$

$7.2\times 600+2.4y=4800\\\Rightarrow y=\dfrac{4800-7.2\times 600}{2.4}\\\Rightarrow y=200$

New cost of jacket = $1.2x=1.2\times 600=720\ \text{sh}$

New costs of skirt = $1.2y=1.2\times 200=240\ \text{sh}$ .
