No it is an irrational number i think
0.83 * 100 = 83, so 0.83 = 83/100.
But in case you meant the slightly more interesting repeating decimal, 0.8333...:
Let <em>x</em> denote this number. Then
10<em>x</em> = 8.333...
100<em>x</em> = 83.333...
==> 100<em>x</em> - 10<em>x</em> = 83.333... - 8.333...
==> 90<em>x</em> = 83 - 8 = 75
==> <em>x</em> = 75/90 = 5/6
Answer:
It takes them 7minutes to finish 50env
Step-by-step explanation:
We know that jerry can stuff 7 in 2min and tom can do 4 per min, so 8 for every 2min.
So 8+7=15env for every 2min 7.5/min
15+15=30+15=45
50=15x/2 50*2=15x 100=15x 100/15=x x=6.67 then rounded it to 7min
