Write the following decimal number in its equivalent fraction form.

Alecsey [184]

Answer:

-0.6666.... = - $\frac{2}{3}$

Step-by-step explanation:

Repeating decimals can be written as either 0.6666..., or as 0.6 with a small line over the top of the 6 to indicate it repeats. Repeating fractions are not put into fractions in the traditional way. If we had the terminating decimal 0.4, then we know to put the 4 over 10 and reduce:

$\frac{4}{10}=\frac{2}{5}$

However, with repeating decimals, instead of putting the number of the decimal over a value of 10, we put it over a value of 9. So, for the equivalent fraction form of -0.6 (repeating) we would get:

$\frac{6}{9}=-\frac{2}{3}$

Snowcat [4.5K]

Answer:

40 square yards

Step-by-step explanation:

The backyard is rectangular and it's dimensions are 7 yards long and 8 yards wide.

The area of a rectangle is given as:

A = L * W

where L = length

W = width

Therefore, the area of the backyard is:

A = 7 * 8 = 56 square yards

Elliana wants to plant sunflowers on 16 square yards of the backyard and the rest of the backyard will be used for a pool.

The area left for the pool will therefore be:

56 - 16 = 40 square yards

40 square yards will be left for the pool.

The equations could you use to find the price of one tire patch is 4x + 1.9 = 22.2.

The price of one patch is $5.075.

Given

To prepare for his mountain biking trip, Rhyan bought four tire patches.

Rhyan paid using a gift card that had $22. 20 on it.

After the sale, Rhyan’s gift card had $1. 90 remaining.

<h3>What is the equation?</h3>

An equation says that two things are equal.

Let, the price of one tire patch be x.

The equations could you use to find the price of one tire patch is;

$\rm = \text{Total number of patches} \times Price \ of \ one \ patch + Remaining \ gift card= Total \ paid \ amount\\\\4x + 1.9 = 22.2\\\\4x=22.2-1.9\\\\4x=20.3\\\\x=\dfrac{20.3}{4}\\\\x=5.075$

Hence, the price of one patch is $5.075.
