You might be able to get the text-to-speech option on your phone to do this for you, since it involves saying the fractions aloud.

1/2 ⇒ one-half

2/3 ⇒ two thirds

1/4 ⇒ one quarter, or one fourth

2/4 ⇒ two fourths, or two quarters

2/5 ⇒ two fifths

5/6 ⇒ five sixths

4/7 ⇒ four sevenths

6/8 ⇒ six eighths

5/11 ⇒ five elevenths

1/12 ⇒ one-twelfth

1/20 ⇒ one-twentieth

_____

IMO, the use of a hyphen or not depends on the context. If the fraction itself is the focus, you might say one twelfth. If it is describing a portion of something else, you might say one-twelfth [of a cake].

coldgirl [10]

the equation to solve these problems is: $\frac{is}{of} = \frac{x}{100}$
1)175*85=100x
x=148.75
2)76*100=80x
x=95
3) 96*100=160x
x=60
4)85*120=100x
x=102
5)56*100=75x
x=74.66

Determine whether the vectors u and v are parallel, orthogonal, or neither.

Natalija [7]

$\mathbf u\cdot\mathbf v=\|\mathbf u\|\|\mathbf v\|\cos\theta$

where $\theta$ is the angle between the vectors. You have

$10\times9+6\times5=\sqrt{10^2+6^2}\sqrt{9^2+5^2}\cos\theta\iff \cos\theta=\dfrac{30}{\sqrt{901}}\implies \theta\approx1.909^\circ$

The vectors would be orthogonal if the dot product had been zero, but that's clearly not the case.

They would be parallel if the angle turned out to be $0^\circ$ or $180^\circ$ , but that's also not the case.

So the answer is neither.

Answer the following questions CORRECTLY I will know if this is wrong. I WILL REPORT ANY INCORRECT ANSWERS!

Kazeer [188]

Answer by JKismyhusbandbae: -12 ≤ f ≤ 6

-3f - 9|-8+8 ≤ 19 + 8

|-3f-9|≤ 27

-3f-9≤ 27 and -3f - 9≥ 27

-3f-9+9≤27+9

-3f ≤ 36

(-3f) (-1) ≥ 36 (-1)3f ≥ - 36

$\frac{3f}{3}$ ≥ $\frac{-36}{3}$
