Question

15m is what percent of 60m; 3m; 30m; 1.5 KM? the last one is km not m

Answer 1

Answer:

1) 15 m is 25% of 60 m

2) 15 m is 500% of 3 m

3) 15 m is 50% of 30 m

4) 15 m is 1% of 1.5 km

Step-by-step explanation:

To find : 15 m is what percent of 60 m; 3 m; 30 m; 1.5 km

Solution :

1) 15 m is what percent of 60 m  

Let the percent be x

So, according to question

15= x% of 60

$15= \frac{x}{100}\times 60$        

$\frac{15\times 100}{60}=x$        

$25=x$        

Therefore, 15 m is 25% of 60 m.

2) 15 m is what percent of 3 m  

Let the percent be x

So, according to question

15= x% of 3

$15= \frac{x}{100}\times 3$        

$\frac{15\times 100}{3}=x$        

$500=x$        

Therefore, 15 m is 500% of 3 m.

3) 15 m is what percent of 30 m  

Let the percent be x

So, according to question

15= x% of 30

$15= \frac{x}{100}\times 30$        

$\frac{15\times 100}{30}=x$        

$50=x$        

Therefore, 15 m is 50% of 30 m.

4) 15 m is what percent of 1.5 km

First we change km into m

1 km=1000 m

1.5 km = 1.5×1000 m

1.5 km=1500 m

Let the percent be x

So, according to question

15= x% of 1500  

$15= \frac{x}{100}\times 1500$        

$\frac{15\times 100}{1500}=x$        

$1=x$        

Therefore, 15 m is 1% of 1.5 km.
