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
[tex]15= \frac{x}{100}\times 60[/tex]
[tex]\frac{15\times 100}{60}=x[/tex]
[tex]25=x[/tex]
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
[tex]15= \frac{x}{100}\times 3[/tex]
[tex]\frac{15\times 100}{3}=x[/tex]
[tex]500=x[/tex]
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
[tex]15= \frac{x}{100}\times 30[/tex]
[tex]\frac{15\times 100}{30}=x[/tex]
[tex]50=x[/tex]
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
[tex]15= \frac{x}{100}\times 1500[/tex]
[tex]\frac{15\times 100}{1500}=x[/tex]
[tex]1=x[/tex]
Therefore, 15 m is 1% of 1.5 km.
