timofeeve [1]

$\large\underline{\underline{\maltese{\red{\pmb{\sf{\: Explanation :-}}}}}}$

The given ratio is 5:8, Write it as fraction then multiply the numerator and denominator with same number to get the fractions or ratios equivalent to the given one.

<em>Let's solve!~</em>

$\rule{300pt}{3pt}$

<em> $\large \sf \: 5 : 8 = \frac{5}{8}$ </em>

<em> $\sf \: \frac{5}{8} \times \frac{2}{2} = \frac{10}{16} \\ \tt \frac{5}{8} = \frac{10}{16}$ </em>

<u>First</u><u> </u><u>equivalent</u><u> </u><u>ratio</u><u> </u><u>is</u><u> </u><u>10</u><u>:</u><u>16</u>

$\rule{300pt}{3pt}$

$\sf \frac{5}{8} \times \frac{4}{4} = \frac{20}{32} \\ \tt \: \frac{5}{8} = \frac{20}{32}$

<u>Second</u><u> </u><u>equivalent</u><u> </u><u>ratio</u><u> </u><u>is</u><u> </u><u>20</u><u>:</u><u>32</u>

$\rule{300pt}{3pt}$

$\sf \: \frac{5}{8} \times \frac{5}{5} = \frac{25}{40} \\ \tt \: \frac{5}{8} = \frac{25}{40}$

<u>Third</u><u> </u><u>equivalent</u><u> </u><u>ratio</u><u> </u><u>is</u><u> </u><u>25</u><u>:</u><u>40</u><u>.</u>

How do I solve for x?

mel-nik [20]

Answer:

x = 4.8

Step-by-step explanation:

Thus:

QP/KJ = PS/JM

Substitute

8/5 = x/3

Cross multiply

5*x = 3*8

5x = 24

x = 24/5

x = 4.8
