Do 18/24 and 10/15 have the same value? Explain your answer in complete sentences.

LenaWriter [7]

Answer:

Step-by-step explanation:

We can either cross multiply or turn into decimal form to see if they have the same value.

I will be showing both.

Cross Multiply: Decimal Form:

$\frac{18}{24} \;[\;\;] \frac{10}{15}$ $\mathrm{To\;turn\;fraction\;into\;decimal\;just}$

$18\times15=270$ $\mathrm{Divide\;numerator \;by \;denominator\;}$

$24\times10=240$ $\mathrm{18\div24=0.75}$

$\frac{18}{24} \;[ > ] \frac{10}{15}$ $\mathrm{10\div15=0.66666666666}$

$\mathrm{As\;a\;result\;we\;can}$ $0.75 > 0.66666666666$

$\mathrm{conclude\;that\;\frac{18}{24} \;is\;greater\;than\;\frac{10}{15}}$ $\frac{18}{24} \;[ > ] \frac{10}{15}$

We can conclude that 18/24 and 10/15 are not the same.

Please help me 20 points

Add up the number of students within the random sample data:
32+26+28+22 = 108

We can then use proportional fractions / cross-multiply to answer the question.

In a sample size of 108 students, 32 of them preferred Movie A.
There are 900 students in total.

$\frac{32}{108} =\frac{x}{900}$

32*900 = 28800

108*x = 108x

108x = 28800

x = $266\frac{2}{3}$ or $\frac{800}{3}$

In decimal form that is approximately 266.667 and round that to the nearest whole number, you get 267 students who would prefer Movie A.
