1) Find x, if 1/3 of x is 14

BartSMP [9]

"of" means multiply and "is" means equal

1. $\frac{1}{3}$ x = 14

x = 14(3) <em>multiply both sides by 3 to isolate "x"</em>

x = 42

2. $\frac{1}{5}$ x = 14

x = 14(5) <em>multiply both sides by 5 to isolate "x"</em>

x = 70

3. $\frac{2}{5}$ x = 14

2x = 14(5) <em>multiply both sides by 5 </em>

2x = 70

x = 35 <em>divide both sides by 2 to isolate "x"</em>

4. $\frac{7}{8}$ x = 14

7x = 14(8) <em>multiply both sides by 8 </em>

7x = 112

x = 16 <em>divide both sides by 7 to isolate "x"</em>

Answer:

1) $n = 84$

2) $n = 78$

3) $n = 24$

4) $n = 16$

5) $n = 35$

Step-by-step explanation:

To solve each proportion, we apply cross multiplication.

Question 1:

$\frac{5}{12} = \frac{35}{n}$

$5n = 35*12$

Simplifying both sides by 5

$n = 7*12 = 84$

Question 2:

$\frac{n}{52} = \frac{180}{120}$

$120n = 52*180$

Simplifying both sides by 20

$6n = 52*9$

Simplifying by 3

$2n = 52*3$

Simplifying by 2

$n = 26*3 = 78$

Question 3:

$\frac{18}{n} = \frac{21}{28}$

$21n = 18*28$

Simplifying both sides by 7

$3n = 18*4$

Simplifying both sides by 3

$n = 6*4 = 24$

Question 4:

$\frac{n}{4} = \frac{24}{6}$

$\frac{n}{4} = 4$

$n = 16$

Question 5:

$\frac{10}{16} = \frac{n}{56}$

$16n = 56*10$

Simplifying by 2, both sides

$8n = 56*5$

Simplifying by 8, both sides

$n = 7*5 = 35$
