Answer:

The height of the building is 30\ ft

Step-by-step explanation:

Let

x--------> the height of the building

y------> the long of the shadow of the building

m----> the height of Will

n-----> the long of the shadow of Will

we know that

By proportion

\frac{x}{y}=\frac{m}{n}

we have

y=18\ ft

m=5\ ft

n=3\ ft

substitute the values

\frac{x}{18}=\frac{5}{3}

3*x=18*5

x=30\ ft

Can someone please write each fraction as a percent and tell me which operation they used? 1. 3/10 2. 2/50 3.7/20 4. 1/5 5.1/8 6
vesna_86 [32]

Answer:

Step-by-step explanation:

Percent literally means hundredth

%=p/100 so

p/100=3/10 so multiply each side by 100

p=300/10

p=30%

p/100=2/50 multiply each side by 100

p=200/50

p=4%

So you can see the pattern here, multiply the fraction by one hundred and you have the ‘percentage’.
