How do i solve problems by finding equivalent ratios

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.

So we can multiply the top and bottom by 2.

0 x 2 = 0
2 x 2 = 4

So an equivalent fraction would be 0/4.

Good luck.

You're on the right track!

920 92 46 23
------ = ---- = ---- = ---
1000 100 50 25

Now we can't go any further, because 23 is prime.

Good luck.

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).

Let x be the number of future weeks.

8 + 4x >= 30

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.

Good luck,

Paul

15 men earns 525
1 man raens 525/15
equals to 35

7 women earns 525
1 women earns 75

so 7 men and 13 women earns 7 *35+13*75=245+975=1220
