Which ratio forms a proportion with 12/15?
r-ruslan [8.4K]

Answer 20/25

When they ask you about ratio, the easy way to reach an answer is by dividing the fraction, in this case if you divide 12 over 15, you'll get 0.8

The same way if you divide 20 over 25. Try yourself if you want to check

The diagram shows a scale drawing of a rectangular banner with a scale of 1:30. Calculate
AlexFokin [52]

Answer:

Part 1) The actual length of the banner is 1.2\ m

Part 2) The area of the banner is 3.24\ m^{2}

Step-by-step explanation:

we know that

The scale of the drawing is \frac{1}{30}

That means ----> 1 cm on the drawing represent 30 cm in the actual

Using proportion

<em>Find out the actual dimensions of the banner</em>

Let

L  the actual length of the banner

W the actual width of the banner

<u>For a length of 4 cm in the drawing</u>

\frac{1}{30}=\frac{4}{L}\\ \\ L=30*4\\ \\L=120\ cm

Convert the actual length to meters

L=120/100=1.2\ m

<u>For a width of 9 cm in the drawing</u>

\frac{1}{30}=\frac{9}{W}\\ \\ W=30*9\\ \\W=270\ cm

Convert the actual width to meters

W=270/100=2.7\ m

<em>Find the area of the banner</em>

A=1.2*2.7=3.24\ m^{2}
