ratios 4:3 and 20:15 are equivalent. If you equate them into fractions it will look like this. 4/3=20/15. if you multiply 4/3 to 5/5 the answer would be 20/15. Therefore, they are equivalent ratios.
Hey Paul,
AN internal combustion engine requires three things to run..(assuming all internals are good)
1. A properly timed spark
2. Proper air/fuel ratio
3. Adequate compression >120psi
Eliminate each of these... one at a time.. you WILL find out why its not running..(this is how a professional trouble shoots a non-running engine!!)
If we have no pizza, and divided it between you and me, how much do we get? ZERO.
However, you want equivalent fractions to 0/2. To get an equivalent fraction, you multiply the numerator (the number on the top) and the denominator (the number on the bottom) by the same number.
Ratios are like fractions: to make an equivalent ratio you simply multiply both sides of the ratio by the same non-zero number. 1:2 is equivalent to 2:4 (both sides multiplied by 2). 10:12 is equivalent to 5:6 (both sides multiplied by 1/2).
Solve for x by subtracting 8 from each side and dividing by coefficient in front of variable. Plug answer into original equation to check that it works correctly.
