What is ⅓ divided by ¼? Use the model if needed. Answer should be in simplest form. Explain your answer

Misha Larkins [42]

Answer:

The answer to the expression in simplest form is:

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

Step-by-step explanation:

Given the function

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

solving to get the simplest form

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a\cdot \:d}{b\cdot \:c}$

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

$\mathrm{Apply\:rule}\:a\cdot 1=a$

$=\frac{4}{3}$

Thus, the answer to the expression in simplest form is:

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

NEED HELP! What is the first step to solve the equation a=2d/t^2 , where a is acceleration, d is the distance, and t is time. If

kondor19780726 [428]

Plug in a = 2 m/s^2 and d = 10 m, and solve for t (in s):

$a=\dfrac{2d}{t^2}\iff2\dfrac{\rm m}{\mathrm s^2}=\dfrac{2\cdot10\,\mathrm m}{t^2}$

$\implies t^2=\dfrac{20\,\rm m}{2\frac{\rm m}{\mathrm s^2}}=10\,\mathrm s^2$

$\implies t=\sqrt{10}\,\mathrm s$

So the answer is C.

If Maria can buy 12 lemons for $2.40, how much will it costs her to buy 16?Set up a proportion to solve.

IgorLugansk [536]

2.40/12 = x/16
then that would mean 12x= 2.40(16)
which equals 12x= 38.4, then divide 12 by both sides, getting you 3.2 so the answer is it would cost her $3.20 cents to by 16 lemons
