Answer:
10.5 hours
Step-by-step explanation:
To find the number of hours she babysat last week subtract 5 from 11 which is 7 hours. 7 hours is equal to 2/3 of the many hours. If she babysat h hours last week then solve for h using 2/3 h = 7.
Solve the equation by multiplying each side by the reciprocal.
3/2 * 2/3h = 7*3/2
h = 21/2
h = 10.5 hours
Find out which fraction is bigger. 1/3 or 1/2
1/3 = 2/6 and 1/2=3/6.
3 > 2
so 1/2>1/3
Hope this helps.
1/7 * 1/2 = 1/14
1/2 because there is a 50/50% chance its either heads or tails
