When reduced to its lowest terms, the fraction 12/16 would read as

3/4

Step-by-step explanation:find the largest common factor that can reduce the numbers. In this case it’s 4. 4x3=12, so we know the numerator can simplify to 3, and 4x4= 16. Therefore we would get a simplified answer of 3/4

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
