Answer: 26/21 or 1 and 5/21
Step-by-step explanation:
Dividing by a fraction is the same as multiplying by the reciprocal, so you can rewrite this problem as (4/6) x (13/7)
Next, multiply the numerators (4 and 13) and the denominators (6 and 7)
You will get 52/42, which can be simplified to 26/21 (you can also write this as 1 and 5/21)
Hope this helps
4 wnd 6 have 2 in common factors
Answer: 65.94 square meters
This value is approximate since pi = 3.14 is approximate

Work Shown:
Area of circle = pi*(radius)^2
A = pi*r^2
Area of smaller circle = pi*2^2 <<--- replace r with 2; which is the smaller radius
Area of smaller circle = 4*pi
Area of larger circle = pi*5^2 <<--- replace r with 5 (since 3+2 = 5); which is the larger radius
Area of larger circle = 25*pi
Area of shaded region = (area of larger circle)-(area of smaller circle)
Area of shaded region = 25*pi - 4*pi
Area of shaded region = 21*pi
Area of shaded region = 21*3.14 <<--- replace pi with 3.14 (approximate)
Area of shaded region = 65.94 square meters
Answer:
Step-by-step explanation:
rea =length × width
7050m^2 = X× 75m
7050 =75X
Divide both sides by 75
7050÷75 =75÷75
74m= X
The errors are that she is just multiplying incorrectly.
10* 1.75 = 17.5
100* 1.75= 175
1000* 1.75 = 1750
When you are multiplying by tens (hundreds and thousands are also considered tens since they are just 10*10 and 10*10*10), you should just be moving the decimal place forward one place.
This goes back to very basic math when you are learning place values.
