On June 21st, there were 9/10 of a billion stars visible to the naked eye.
On December 21st, there were 4/5 of a billion stars out visible to the naked eye.
How many times more stars were there visible on June 21st than December 21st?
SOLUTION:
1): Set it up. 9/10 divided by 4/5=?
2): Find the reciprocal of the divisor.
9/10 × 5/4=?
3): Simplify. 9/10 × 5/4= 9/2 × 1/4
4): Solve. 9/2 × 1/4=9/8
5): Simplify again. 9/8= 1 1/8
OUR ANSWER IS 1 1/8!!!
