What is the quotient of 4 2/3 divided by 4 1/5 :fraction

2 answers:

8 0

Write the two fractions as improper fractions
4 2/3 is 14/3
<span>4 1/5</span> is 21/5
rewrite
14/3 <span>÷ 21/5
since it is pretty complicated to divide two fractions,
you change it to multiplication
keep the first fraction, change the division sign to multiplication, then flip the second fraction
(you can remember KEEP, CHANGE, FLIP whenever dealing with division of fractions :) )
14/3 * 5/21
multiply across
(14 * 5) / ( 3 * 21)
</span>70/ 63
simplify to 10/9
this can be written as 1 1/9

Hope this helps

Answer:

1 1/9

Step-by-step explanation:

Write the two fractions as improper fractions

4 2/3 is 14/3

4 1/5 is 21/5

rewrite

14/3 ÷ 21/5

since it is pretty complicated to divide two fractions,

you change it to multiplication

keep the first fraction, change the division sign to multiplication, then flip the second fraction

(you can remember KEEP, CHANGE, FLIP whenever dealing with division of fractions :) )

14/3 * 5/21

multiply across

(14 * 5) / ( 3 * 21)

70/ 63

simplify to 10/9

this can be written as 1 1/9

A sector of a circle makes a 127° angle at its centre. If the arc of the sector has length 36 mm, find

Veseljchak [2.6K]

Answer:

Approximately $68.5\; \rm mm$ .

Step-by-step explanation:

Convert the angle of this sector to radians:

$\begin{aligned}\theta &= 127^{\circ} \\ &= 127^{\circ} \times \frac{2\pi}{360^{\circ}} \\ &\approx 2.22\end{aligned}$ .

The formula $s = r\, \theta$ relates the arc length $s$ of a sector of angle $\theta$ (in radians) to the radius $r$ of this sector.

In this question, it is given that the arc length of this sector is $s = 36\; \rm mm$ . It was found that $\theta = 2.22$ radians. Rearrange the equation $s = r\, \theta$ to find the radius $r$ of this sector:

$\begin{aligned} r&= \frac{s}{\theta} \\ &\approx \frac{36\; \rm mm}{2.22} \\ &\approx 16.2\; \rm mm\end{aligned}$ .

The perimeter of this sector would be:

$\begin{aligned}& 2\, r + s \\ =\; & 2 \times 16.2\; {\rm mm} + 36\; {\rm mm} \\ =\; & 68.5\; \rm mm\end{aligned}$ .

What is the slope of a line perpendicular to the line whose equation is 15x−18y=−486. Fully simplify your answer.

bazaltina [42]

The answer is -6/5

First convert the equation to y=mx+b form
you’ll get y=5/6x+27
then to find the line perpendicular to this equation, you have the flip the slope.
ending with -6/5
