Answer:
Step-by-step explanation:
multiplying fractions is usually super simple. You just multiply the top numbers and multiply the bottom numbers. So 2/3 * 5/7 = (2*5)/(3*7) = 10/21.
Here you have mixed fractions. For me, the easiest way is to make them improper fractions and then multiply them. So 2 and 3/4 becomes 11/4 and 1 and 13/20 becomes 33/20. Let me know if you don't get that.
Anyway, if we make the unknown fraction x we can rewrite this as an algebraic equation.
(11/4)x = 33/20 Now just multiply both sides by 4 and divide both sides by 11 and you will get
x = 3/5
Again, let me know if there's something you don't understand.
The first person who calculated pi was <span>Archimedes got really close however with the mathematics he had in his time he did not have decimal points nor could he use the number 0. So it has to latter once people recognize 0 as a number and the decimal point that we get what we have today. </span><span />
Answer:
d) 2 1/2
Step-by-step explanation:
if you make 5/2 a mixed number, you get 2 1/2
Shannon's scooter has a piece of tape stuck to the tire. If
the tire has a diameter of 18 inches, the distance traveled by the piece of
tape in 72 degree rotaion can be solve using:
S= ra, where s is the distance traveled, r is the radius and
a is the angle in radians
s = (18in/2)(72 degree)(pi/180 degrees) = 11.31 in.
