Simplify: -1 | 2/3 - 4 | / 5/6
stealth61 [152]

Answer:

<h3>4</h3>

Step-by-step explanation:

- 1 | \frac{2}{3}  - 4|  \div  \frac{5}{6}  \\  - 1 | \frac{2}{3} -  \frac{4 \times 3}{1 \times 3}  |  \div  \frac{5}{6}  \\  - 1 | \frac{2 - 12}{3} |  \div  \frac{5}{6}  \\  - 1 | \frac{ - 10}{3} |  \div  \frac{5}{6}  \\  \frac{10}{3}  \div  \frac{5}{6}  \\  \frac{10}{3}  \times  \frac{6}{5}  \\  \frac{2}{1}  \times  \frac{2}{1} = 4

beginning at sea level a scuba diver dove 1 2/3 feet into the water , and then dove an additional 3 2/5 feet at what elevation i
skad [1K]

The given details are illustrations of addition and subtractions of fractions.  The scuba driver is at an elevation of -5\frac{1}{15} ft below the sea  level.

Given that:

n_1 = 1\frac 23 --- the first dive

n_2 = 3\frac 25 ---- the additional dive

From the question, we understand that the diver starts at the sea level.

This is represented with 0ft.

So, the diver's elevation (d) is calculated as follows:

d = 0 - n_1 - n_2 --- we use subtraction because the diver is below the sea level

So, we have:

d = 0 - 1\frac 23 - 3\frac 25

d = - 1\frac 23 - 3\frac 25

Convert fractions

d = - \frac 53 - \frac{17}5

Take LCM

d = \frac{-5 \times 5 - 17 \times 3}{15}

d = \frac{-76}{15}

Reduce fraction

d = -5\frac{1}{15}

The above value means that the diver's elevation is at -5\frac{1}{15} ft below the sea  level.
