The best way to do this is to set up a proportion

3        12

then cross multiply and divide ( 50 times 12) / 3= 200

he can do 200 situps in 12 minutes

Type a digit that makes this statement true.
Archy [21]

Answer:

So information at the bottom:

since every number in a thousand spot needs to have 3 digest, we need to add a zero onto 29,422,33<u>0</u>. If we didn’t add a zero, then the problem wouldn’t make much since. So if we divide 29,422,330 by 2, our answer would be 14,711,165. A whole bunch of numbers, but nothing that can’t be solved!

<h3>Hope this helps!✌️</h3>
