Kiara bought cupcakes for her sister's birthday party. 25% of the 72 cupcakes had sprinkles

kobusy [5.1K]

First we must find the percentage of our number

Because our number is 72 we have to find 25% of it

Simple way

<em>25% of 72 is another way of saying 25% times 72</em>

<em />

25% x 72

= 18

Answer

Therefore 18 of Kiara's cupcakes had sprinkles.

<em>P.S: if you want you can multiply in fraction form and still get the same answer</em>

<h3><u>Question:</u></h3>

Serena uses chalk to draw a straight line on the sidewalk. The line is 1/2 ft long. She wants to divide the line into sections that are each 1/8 ft long. How many sections will the line be divided into?

<h3><u>Answer:</u></h3>

The number of sections that the line is divided is 4

<h3><u>Solution:</u></h3>

Given that, Serena uses chalk to draw a straight line on the sidewalk

The line is 1/2 ft long. She wants to divide the line into sections that are each 1/8 ft long

From given,

$Total\ length\ of\ line = \frac{1}{2} \text{ feet }\\\\Length\ of\ each\ section = \frac{1}{8} \text{ feet }$

To find: Number of sections can be made

The number of sections that can be made is found by dividing the total length of line by length of each section

$\text{Number of sections } = \frac{\text{Total length of line}}{\text{length of each section}}$

Substituting the values, we get,

$\text{Number of sections } = \frac{\frac{1}{2}}{\frac{1}{8}}\\\\\text{Number of sections } = \frac{1}{2} \times \frac{8}{1}\\\\\text{Number of sections } = 4$

Thus number of sections that the line is divided is 4

The length, width, and height of a rectangular solid are 13.5, 12, and 14.1, respectively. Find the volume.

Finger [1]

You have to multiply the length by the width and the sum of that you will multiply by the height. In this case 13.5 times 12 is 162. So 162 times 14.1 is 2284.2
