Jack is learning to ride a bicycle. in his first try, he rode for 4/100 mile, the second time he rode for 6/100 mile. in the next two tries, he rode successfully for 2/10 mile and 3/10 mile. what is the total distance, written as a fraction, that jack rode the bike in four tries? what decimal number is equal to the total distances that jack rode his bike?

In the question , it is given that Jack is learning to ride a bicycle. in his first try, he rode for 4/100 mile, the second time he rode for 6/100 mile. In the next two tries, he rode successfully for 2/10 mile and 3/10 mile.

We have to find the total distance , and for that we have to add all the distances he rode, that is

Making all the denominator equal, by multiplying the last two numerators and denominators by 10

Now since the denominators are same, so we have to add the numerators, that is

In the second part, we have to find the total distance travelled in decimal , which is 0.6 miles .

70

step-by-step explanation:

2*5=10

4*15=60

60+10=
