To find fractions that are equivalent to 4/7, just multiply the numerator and denominator by a number.
4/7 X 2/2 = 8/14.
4/7 X 3/3 = 12/21.
4/7 X 4/4 = 16/28.
4/7 X 5/5 = 20/35.
4/7 X 6/6 = 24/42.
4/7 X 7/7 = 28/49.
4/7 X 8/8 = 32/56.
4/7 X 9/9 = 36/63.
4/7 X 10/10 = 40/70.
The bolded fractions are equivalent to 4/7.
I am going to go with choice A
A(n)=A(n-1)+17 with A(1)=3
What is inside the parentheses can also be written as a subscript.
Hope this helps!
The scale that will produce the smallest drawing would be b) 1mm:50m.
First, I converted all the measurements to centimeters:
a) 1cm:500cm
b) 0.01cm:5000cm
c) 5cm:1000cm
d) 10cm:2500cm
Then, you divide the scales:
a) 0.002
b) 0.000002
c) 0.005
d) 0.004
B is the smallest number, meaning it will be the smallest scale.
