Cual es el resultado de truncar a milésimos (3 decimales) 2/7 cuando lo convertimos a número decimal

Whitepunk [10]

The value of 2/7 expressed as a truncated decimal to the nearest thousandth is 0.286

Rational numbers are numbers written as the ratio of two integers. For example, the fraction 2/7 given is a rational number.

Expressing 2/7 as a decimal number will give;

2/7 = 0.2857142... (It gave repeated decimal values)

Truncating the repeating decimal to the nearest thousandth means writing the decimal to 3 decimal places

0.2857142 = 0.286 (to the nearest thousandth)

Hence the value of 2/7 expressed as a truncated decimal to the nearest thousandth is 0.286

myrzilka [38]

Answer:

$1\frac{3}{4}$

Step-by-step explanation:

In order to find the answer, you first need to convert the mixed number (2 1/3) into a improper fraction and then multiply.

$\frac{3}{4} \times2\frac{1}{3}$

$2\frac{1}{3} =3\times2=6+1=7=\frac{7}{3}$

$\frac{3}{4} \times\frac{7}{3}$

$3\times7=21$

$4\times3=12$

$=\frac{21}{12} =\frac{7}{4} =1\frac{3}{4}$

$=1\frac{3}{4}$

Hope this helps.

It takes William 45 minutes to weed the garden. It takes his younger sister May 75 minutes to do the same job. If they work toge

marshall27 [118]

Answer:

B. 28 minutes

Step-by-step explanation:

According to the given statement,

William weeds the whole garden in 45 minutes, then in one minute he will weed 1/45 of the garden

and

similarly, 1/75 of the garden in one minute.

When they both will work together, they will weed (1/45+1/75) of the garden in one minute

Solving the equation:

= $\frac{1}{45}+ \frac{1}{75}\\= \frac{75+45}{3375}\\ =\frac{120}{3375}\\ = 0.036$

Garden weeded in one minute by both = 0.036

So, number of minutes to weed whole garden = 1/0.036

= 27.77 minutes

Rounding off will give us: 28 minutes

So,

Option B is the correct answer ..
