$3 \text{ ":" } 1$

#### Explanation:

Before numbers can be written as a ratio they need to be in the same unit.

$1 \frac{1}{4} \text{hr ":" "25"min"" } \leftarrow$ change to minutes

$75 \text{min ":" "25"min } \leftarrow$ drop the units

A ratio is given in the simplest form: Divide by the HCF

$75 \div 25 \text{ ":" } 25 \div 25$

$\text{ "3" ":" } 1$

$1 : 3$

#### Explanation:

To find ratio of the two, weshould first convert them first to same units.

One hour is $60$ minutes and as such $\frac{1}{4}$ hour is $\frac{1}{4} \times 60 = 15$ minutes and $1 \frac{1}{4}$ hours is $60 + 15 = 75$ minutes.

Hence $25 \text{minutes":1 1/4"hours}$

is $25 \text{minutes":75"minutes}$

and as $\frac{75}{25} = 3$, the ratio is $1 : 3$
