Alejandro uses the steps below to convert

dezoksy [38]

Answer:

The division was computed incorrectly.

Step-by-step explanation:

Given

Workings:

$\frac{5}{8}$ to percentage

$\frac{8}{5} = 1.6 = 160\%$

Required

Explain his error

The question says 5/8

Instead, Alejandro's working shows 8/5.

This working is done in an incorrect order and the correct solution is:

Let

$x = \frac{5}{8}$

Solve the fraction

$x = 0.625$

Multiply by 100%

$x = 0.625 * 100\%$

$x = 62.5\%$

<em>Hence, option (a) is correct.</em>

If y varies directly with x and y is -6 when x is 2, what is x when y is -22?

zubka84 [21]

Answer:

x = $\frac{22}{3}$

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = - 6 when x = 2, then

- 6 = 2k ( divide both sides by 2 )

- 3 = k

y = - 3x ← equation of variation

When y = - 22, then

- 22 = - 3x ( divide both sides by - 3 )

x = $\frac{-22}{-3}$ = $\frac{22}{3}$
