Answer: 7/8= 35/40
3/10= 12/40
Step-by-step explanation: You can find the least common denominator by looking at a multiplication table or by multiplying the prime factors of the original denominators:
8 = 2×2×2. 10=2×5
"Cancel" the duplicate from one set or the other. So here one of the 2's is eliminated:
2×2×2×5=40
Then set up a proportion:
7/8 = x/40 Multiply the new denominator by the original numerator, then divide by the original denominator:
40×7=280. 280÷8=35
40×3=120. 120÷10=12

Answer:
Area = 
Step-by-step explanation:
The area of the shaded region is equal to the total area of the full square minus the area of the non shaded region.
The area of a rectangle is its base times its high
So A=b*a.
For the full square, A1=
For the non shaded square, A2 = 
So the shaded area is A1-A2 = 
Answer:
$338.20
Step-by-step explanation:
First, lets find out how much Kim makes in 1 hour
SO, we can do $89÷10 which is $8.9 per hour
