Oscar is making vegetable soup. he uses 9 carrots for every 5 parsnips.
write down the ratio of carrots to parsnips by filling in the missing numbers.
:
oscar uses 27 carrots. how many parsnips does he use?

The original would be 9:5 (9 carrots every 5 parsnips). Because he used 27 carrots, you would multiply 9:5 by 3 (9x3 is 27) which leaves you with 27:15 ... hope i helped :)

The ratio of carrots to parsnips is 9:5.
To find the answer to the second question write the ratio as an fraction and equal it to the number of carrots over the number of parsnips.
Ratio: 9/5
Number of Carrots: 27
Number of Parsnips: x
Equation: 9/5 = 27/x
Cross multiply---     9x = 27*5
Simplify---     9x = 135
Simplify---     (9x)/9 = 135/9
Simplify---     x = 15

If there are 27 carrots, Oscar needs to use 15 parsnips for the vegetable soup.
