Explanation:

her ratio is therefore 25/10, which can be also written as 5/2, because ratios are just a special form of fractions.

to find how many labels she can type in 1 hour, we need to find the rehashing between 10 minutes and 1 hour.

1 hour = 60 minutes.

60 minutes = 6 × 10 minutes.

so, to find the equivalent ratio based on 1 hour, we need to multiply the denominator (bottom part) by 6.

and to keep the ratio value we need to multiply the numerator (top part) by the same number :

25/10 × 6/6 = 150/60

and since the ratio is always telling us how many labels can be typed per unit of time, we see,

she can type 150 labels in 1 hour (60 minutes)
