If a ration is also a fraction, and your wording is correct than an enlargement of 1:3 where 1 is the original shape would suggest that the 3 would be that same original shape, be enlarged in terms of 3 compares to 1 so a 300% enlargement.

if the original rectangle has a 16 cm perimeter, than the new rectangle has a 48 cm perimeter.

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.

Solve for x: 1 < x + 3 < 4

Pani-rosa [81]

undo what's done to x:

-2 < x < 1

this SHOULD be your answer-- if it's not for some reason, let me know.
