Answer: she needs to babysit 4 more times.
Step-by-step explanation:
The correct answer is 28.3.
You take 22/1.4 and get 15.7142857143. Then you take 15.7142857143*1.8 which equals 28.2857142857 so you round it up to 28.3 which is the answer.
I hope this helps you:)
To multiply fractions, you multiply numerator with numerator and denominator with denominator
In other words: a/b*c/d=(a*c)/(b*d)
So 1st one is (5*2)/(6*3) which is 10/18 or 5/9 simplified
2nd one is (9*5)/(10*18) which is 45/180 or 1/4 simplified
3rd one is (4*3)/(5*4) which is 12/20 or 3/5 simplified
4th one is (2*5)/(3*1) which is 10/3 or 3 1/3 if you want a mixed number
Hope this helped!
