Answers
Step-by-step explanation:
1-(7/10+1/6)=1-(21+5)/30
1-26/30
1-13/14
=14-13/14
Answer:
2/15
Step-by-step explanation:
To find the number that walk we need to take the fraction that drive or bus to school away from the total.
1 - 7/10 - 1/6 = ?
to combine the fractions 7/10 and 1/6 so we can add them together we need to make the denominator (bottom number) the same. To do this easily we multiply the top and the bottom of the first fraction by the denominator of the second. This doesn't change the ratio but scales the top and botom numbers by the same amount.
7 / 10 = (7*6) / (10*6) = 42/60
Then do the same for the second fraction but multiply top and bottom by the denominator of the first fraction
1/6 = (1*10) / (6*10) = 10 / 60
Now the denominators are the same we can add them together and then simplify.
42/60 + 10 / 60 = 52/60 = 13/15
so now we have 1 - 13/15 = 2/15
