Oatmeal is made by mixing 15 cups of hot water to 6 cups of oats.

skad [1K]

9514 1404 393

Answer:

2/5 cups oats per cup water
2.5 cups water per cup oats

Step-by-step explanation:

The denominator of the fraction is the unit you want 1 of.

(6 cups oats)/(15 cups water) = (6/15) cups oats/(1 cup water)

= (2/5 cups oats)/(1 cup water)

1 cup of water would need 2/5 cups of oats.

Obviously, the other ratio is the reciprocal of this.

(1 cup water)/(2/5 cups oats) = (5/2 cups water)/(1 cup oats)

1 cup of oats would need 2.5 cups of water

A bicycle that usually sells for $230 is on sale for 15% off. Find the sale price.

nikitadnepr [17]

$\frac{15}{100} = \frac{x}{230 } \\ x = \frac{15 \times 230}{100} = \frac{3450}{100 } = 34.5$
15% of $230 is $34.5
$230 - 34.5 = 195.5$
so the price is $195.5
hope this helps
