WHAT ARE EQUIVALENT RATIOS
EQUIVALENT RATIOS ARE: Ratios that look different but name (show) the same
comparison as the original.
EX:
2 = 4
4
8
2 apples to 4 oranges
4 apples to 8 oranges
2:4
4:8 ( the ratio is the same, but
there are 2 groups; it doubled)
HOW DO YOU MAKE EQUIVALENT RATIOS?
There are 2 ways to find equivalent ratios:
1) MULTIPLYING:
MULTIPLY
or
DIVIDE
If you want LARGER but EQUAL ratios
4
6
x2
x3
x4
8
12
12
18
16
24
 You X’s both the top & bottom number of the original ratio by the same number.
 You can multiply by any numbers – they DO NOT have to be in a number sequence
( BUT they must go from smaller to larger in value ex: 2,5,10)
