To make a dark orange color, Ron mixes 3 ounces of red paint with 2 ounces of yellow paint. Write the ratio of red paint to yellow paint three ways

Answer 1

Set the problem up like a ratio fraction:

^{3 red ounces} / _{2 yellow ounces}

If you want to leave the names out of the way for the mathematics, then that's fine:

³/₂

What you do now is essentially multiply this by ratios of one. Let me explain:

²/₂ = 1; ⁴/₄ = 1; ³⁶⁷¹²/₃₆₇₁₂ = 1

I'll give you one to see what happens:

³/₂ * ²/₂ = ^{6 red ounces} / _{4 yellow ounces}

The numerator multiplies with the numerator, and the denominator multiplies with the denominator.

Now you can find other ratios. Try ³/₃ and ⁴/₄ on your own.
