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>

HELP MEEE PLS recipe cslls for 2 cups of suger and makes 48 cookies recipe B calls for 3 cups of suger and makes 54 of the same

JulijaS [17]

Answer:

So, when we solve for x we see that we can make 16 cookies using 1 cup of sugar. Then, yes, as you suggested we could divide 30 cookies by this ratio to see that we need less than 2 cups of sugar to make 30 cookies: And, as you said, this value is less than 2 cups, the value under Quantity B. Good job! I hope this helps :)
