One way to write a ratio, is as a fraction. For example, you have 6/8, right, so now you basically rewrite that, but instead of the (/) sign, you put the (:) sign, which we normally use for writing ratios. That's the most common way of writing ratios, but also, you can do this;
*you have the same fraction, 6/8, but you basically say it in words. (six to eight) that's exactly how you would say it in words. Remember, your first number thats given is the number you ALWAYS write, or say first

There are 3 different ways to write a ratio this first is a fraction, 5/8. You could also write it using the word "to", 5 to 8. Finally you could write it using a colon, 5:8. Hope this clears things up for you!

There was no actually pyramid for these questions it tells you the measurements in the problem though. please help me

V=448 in^3
l=8 in
w=12
h=?
V=l•w•h/3
448=8•12•h/3 multiply both sides by 3
3•448=96•h
1344=96•h
h=1344/96
h=14 in


V=l•w•h/3
h=4in
l=3in
w=2.5 in
V=?
V=4•3•2.5/3
V=30/3
V=10 in^3

Write a real-world problem that can be modeled by the equation 1.25x=0.75x+50
dimulka [17.4K]
We have such equation
1.25x=0.75x+50        /-0.75x   (subtract 0.75 both sides)
1.25x-0.75x=0.75x-0.75x+50
0.5x=50          /*2   (multiply both sides times 2)
0.5x*2=50*2
x=100 - its the answer
