You are on an alien planet where the names for substances and the units of measures are very unfamiliar.

Nonetheless, you obtain 29 quibs of a substance called skvarnick.

You can trade this skvarnick for gold coins, but the vendors all measure skvarnick in units of sleps; not quibs.

10 quibs is equal to 4 sleps.

If you have 29 quibs of skvarnick, how many sleps do you have?

Round your answer to the nearest tenth (one decimal place).

So a quib seems to be a unit of measure

and we have another unit called sleps

so sleps:quibs is some ratio

oh nice, 10quibs:4sleps

yo have 29 quibs

easy

29quibs:? sleps=10quibs:4sleps

ratio and proportion

29/?=10/4

times both sides by 4?

(4) (29) = 10?

116=10?

divide both sides by 10

11.6=?

you have 1 11.6 sleps

anohter way

10quibs=4sleps

divide by 10 both sides

1quib=4/10 sleps=2/5 sleps

times 29 both sides

29 quibs = (29*2) / 5=58/5=11.6 sleps

yo has 11.6 sleps
