Lunna [17]

Answer:

1/10

Step-by-step explanation:

1

Find the Least Common Denominator (LCD) of 25,12\frac{2}{5}, \frac{1}{2}​5​​2​​,​2​​1​​.

Method 1: By Listing Multiples

List out all multiples of each denominator, and find the first common one.

Multiples of 5

: 5, 10, ...

Multiples of 2

: 2, 4, 6, 8, 10, ...

Therefore, the LCD is 101010.

Method 2: By Prime Factors

Since 5,25,25,2 are prime numbers themselves, we simply multiply them to get the LCD.

Therefore, the LCD is 5×2=105\times 2=105×2=10.

LCD = 101010

2

Make the denominators the same as the LCD.

−2×25×2+1×52×5-\frac{2\times 2}{5\times 2}+\frac{1\times 5}{2\times 5}−​5×2​​2×2​​+​2×5​​1×5​​

3

Simplify. Denominators are now the same.

−410+510-\frac{4}{10}+\frac{5}{10}−​10​​4​​+​10​​5​​

4

Join the denominators.

−4+510\frac{-4+5}{10}​10​​−4+5​​

5

Simplify.

110\frac{1}{10}​10​​1​​

Straws are shipped into a box with dimensions of 6.0x6.0x8.0 inches. Each straw is 3/8 inches wide and 7 and 3/4 inches long. Ho
sattari [20]

Answer:

256

Step-by-step explanation:

First, let's see the height of the box (8 inches) is long enough for one straw (7 inches and 3/4) but not enough for 2... so there could be only one layer.

Now the box is a prism with a square base (6 inches each side).

How many straws can we fit on one side?  We have to divide the width of the box by the width of a straw.  

row = \frac{6}{3/8} = \frac{48}{3} = 16

We can fit 16 straw per 6-side side of the box... Since the box is 6x6 inches, we can then fit 16 x 16 straws in it... 256 total.
