A horse can run 1 3/8 of a mile in 1 3/5 minute. How long does it take the horse to run 1 mile?
So what i would personally do first is convert the fractions into decimals.

Step-by-step explanation:
Hello There!
Remember the exterior angle of a triangle is equal to the opposite interior angles of a triangle
so
137-x=2x+3x-1
now we can solve for x
step 1 combine like terms
2x+3x=5x
now we have
137-x=5x-1
step 2 add 1 to each side
-1+1 cancels out
137+1=138
138-x=5x
step 2 add x to each side
-x+x cancels out
5x+x=6x
now we have
138=6x
step 3 divide each side by 6
6x/6=x
138/6=23
we´re left with x=23
Well, the 2 in 582 is in the ones place and the 2 in528 is in the tens place so
2 and 20
one is 10 times the other
they are both multiples of 2
