Answer:
7 + 11 + 11
Step-by-step explanation:
7 + 11 = 18
18 + 7 = 25
7 pens and 20 pencils because 28 divided by 4 = 7 and 80 divided by 4 = 20
So the ratio of boys to girls is 12:24.. now, is that an equivalent ratio as 2 boys for 4 girls? or 2:4? let's see.

you could start simplifying the 12/24 fraction by dividing by some common multiple, say 2, and get 6/12, then divide by 3 and get 2/4 and stop there.
then you'll notice that 12/24 is really 2/4 in disguise.
Answer:
cubic units
Step-by-step explanation:
Volume of the square pyramid is given as ⅓*area of base*height of pyramid.
Where,
Area of base = 6*6 = 36
Height of pyramid = altitude =
units
Plug the values into the formula to find volume.


cubic units
It's 1/3 which can = 0.3333...
