18 to 29=10%

1 answer:

3 0

45 people is 10% of 450.
So how many people is 30% of 450.

1. Multiply (45)(3) = 135. Because 30% is 3 times 10%.
2. Multiply (450)(.3) = 135. Because .3 = 30% in decimal form.

A rectangular prism with a volume of 44 cubic units is filled with cubes with side lengths of 1/3 unit How many 1/3 unit cubes d

pickupchik [31]

Check the picture below.

so the volume of the smaller cube will just be (1/3)³.

how many of those cubes will take to fill up the larger cube?

namely

how many times does (1/3)³ go into 44?

$\bf \left( \cfrac{1}{3} \right)^3\implies \cfrac{1^3}{3^3}\implies \cfrac{1}{27}\impliedby \textit{volume of the smaller cube} \\\\\\ 44\div \cfrac{1}{27}\implies \cfrac{44}{1}\div \cfrac{1}{27}\implies \cfrac{44}{1}\cdot \cfrac{27}{1}\implies 1188$
