67 but why couldn’t u just use a calc
Give me a sec I’m going to answer
A material made of two or more compounds where the components aren't chemically combined is called a mixture. They both keep their individual chemical properties and their chemical makeup isn't affected by the combination.
Hope this helps!
P r o p o r t i o n s
3:4 = 7
3/198 = 7/x
solve for x using cross multiplying
3/198 = 7/x
198(7) = 3x
1386 = 3x
/3 /3
462 = x
Therefore, there are 462 workers.
Proof:
3/198 = 4/x
198(4) = 3x
792 = 3x
/3 /3
264 = x
264 + 198 = 462.
264 / 4 = 66
198 / 3 = 66
462 / 7 = 66
