there is 4/5 lb of sand in science supplies. if one scoop of sand weighs 1/20 of a lb how many scoops of sand can maria get from

tatuchka [14]

We want to divide whole sand into scoops, so we have to divide 4/5 by 1/20. Lets do this

$\frac{ \frac{4}{5} }{ \frac{1}{20} }$
We know that if we want to divide 2 fraction we can multiply first by inverse of second fraction instead of dividing.,so:
$\frac{ \frac{4}{5} }{ \frac{1}{20} }$
$\frac{4}{5}* \frac{20}{1}= \frac{4*20}{5*1} = \frac{80}{5}= 16$ scoops - its our result.

ki77a [65]

First you need to know the definition of a complementary angle. That means that two angles add up to 90 degrees, or a right angle.
