Answer:
Step-by-step explanation:
First, write an equation. 55x+40=190.
X represents the hours the electrician works. The 55 represents the $55 that she charges for each hour she works. The +40 for the $40 that was the price just to come to your house. The 190 is the total cost. Now, solve that equation.
55x+40=190
55x=150
x=2.72727272...
So the answer is 2.727 hours. It can be rounded as needed or turned into a decimal, 2 8/11.
The ratio is 9:81 which is equivalent to 1:9
Answer:
6/5 or 1 1/5
6/5 is an improper fraction, so I didnt know if youd need an improper one or a proper one. They both are the same thing though :)
Step-by-step explanation:
4/10*3
They both need to be a fraction, and any number over 1 = that number. So,
4/10*3/1
4*3=12
10*1=10
12/10
Then, you have to simplify the fraction.
6/5 (bc 2 goes into 12 6 times and 2 goes into 10 5 times)
or 1 2/10= 1 1/5
