Write 12.04 as a mixed number ( this means standard form as a fraction)

12  1/25

Step-by-step explanation:

First, write the decimal as a fraction. To do this you can leave the 12 alone and just use the .04. This becomes 4/100 because the 4 is in the hundreds place.

Then simplify by finding the least common factor, in this case 4, and dividing both the numerator and denominator by this. This results in 1/25.

Finally add them together to get, 12 1/25.

sorry not knowing about that

the distance between the school and her home is 3.6km.

12 mins = 0.2 hours = 1/5 hour

54 ÷ 3 = 18km per hour

1/5 of 18 = 3.6km per 12 mins
