Move the place value of the decimal to the right two place values and set the number over 100
0.45 = 45/100
45/100 can be one of your answers
Hope this helps
X=4. First, you do 15/12 and get 1.25. You do this to see what number you have to multiply 12 to, to get 15. Since the sides a proportional it should be the same for the sides with their variables. Then you create an expression that puts the numbers the same place where 15 and 12 were to equal 1.25. You cross multiply, solve and get 4.
.05
You just move the decimal place back, twice.
When Brooks painted more he used 6/12 of what was left(1/2 of what was left)
