Hint
Help VideoCorrect
Great Work!
Incorrect
A ratio compares quantities of the same type given in the same units.Convert the ratios into fraction form and solve for `m`.`5:3` `=` `m:12` `5/3` `=` `m/(12)` Convert to fraction form `3(m)` `=` `5(12)` Cross multiply `3m``divide3` `=` `60``divide3` Divide both sides by `3` `m` `=` `20` `m=20` -

Hint
Help VideoCorrect
Correct!
Incorrect
A ratio compares quantities of the same type given in the same units.Convert the ratios into fraction form and solve for `a`.`6:24` `=` `2:a` `6/(24)` `=` `2/a` Convert to fraction form `6(a)` `=` `2(24)` Cross multiply `6a``divide6` `=` `48``divide6` Divide both sides by `6` `a` `=` `8` `a=8` -

Keep Going!
Incorrect
A ratio compares quantities of the same type given in the same units.Convert the ratios into fraction form and solve for `x`.`4:5` `=` `16:x` `4/5` `=` `(16)/x` Convert to fraction form `4(x)` `=` `16(5)` Cross multiply `4x``divide4` `=` `80``divide4` Divide both sides by `4` `x` `=` `20` `x=20` -

Fantastic!
Incorrect
A ratio compares quantities of the same type given in the same units.Write the problem in equation form and let `x` be the unknown value`4:5` `=` `5.40:x` Convert the ratios into fraction form and solve for `x`.`4:5` `=` `5.40:x` `4/5` `=` `(5.40)/x` Convert to fraction form `4(x)` `=` `5.40(5)` Cross multiply `4x``divide4` `=` `27``divide4` Divide both sides by `4` `x` `=` `6.75` `$6.75`
