Question

The soil in Sean's backyard is made up of 45% sand. If he has 1000 lbs of soil in his yard, how many pounds of sand are there?

Answer 1

Answer: 450 lbs

Step-by-step explanation:

45/100 is 45%

Since there are 1000 lbs we multiply 45/100 by 10, giving us 450/1000

Therefore 45% of 1,000 is 450

Answer 2

450 pounds of sand is present in the soil.

What is percentage?

'A percentage is a number or ratio expressed as a fraction of 100. A percentage is a dimensionless number, that is, it has no unit of measurement.'

Total weight of soil in Sean's backyard = 1000 pounds

Percentage of sand in the soil = $\frac{45}{100}$

Total amount of sand in the soil = ( $\frac{45}{100}$ × 1000 ) lbs

                                                     = 450 lbs

Hence, we can conclude, 450 pounds of sand is present in the soil in Sean's backyard.
