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
start by writing the multiplication in this form
start multiplying from right to left.

write the first number down
continue by multiplying the next number from right to left

write the number down, since there are no more numbers to multiply for write the wole number
this means that
Divide the numerator by the denominator .
Harmonic mean between two positive numbers x and y, The simplified formula is
I.e. you need to double the product of x and y then divide it by the sum of x and y...~
