2 1/4 miles => 1 week
1 mile => 1 ÷ 9/4
( 9/4 is an improper fraction of 2 1/4 )
12 1/2 miles => ( 1 ÷ 9/4 ) × 25/2
= 50/9
= 5 5/9 weeks
( 25/2 is an improper fraction of 12 1/2 )
Therefore, it will take 5 5/9 weeks for the company to replace the stretch of road.
( you can round it off to 6 weeks if the qn specify to give to the nearest whole number )
12,419,293
an increase of 100,000 = 12,519,293
an increase of 1,000,000 = 13,419,293
a decrease of 10,000 = 12,409,293
You multiply the 2 values together to get 1.5*10^12
X = 5
So 3x = 3(5) = 15
3x = 15
