The last option :) Ask if explanation needed
16/10 as a mixed number is 1 6/10.
I got this answer by finding out how many times 10 goes into 16, evenly. I got 1, and put that as a whole number. 6 was leftover, so I put that for the numerator. Then, I kept the denominator same, which was 10.
1 6/10 simplified is 1 3/5.
I got this answer by finding out what number goes both into 10 and 6, evenly. The GCF, or Greatest Common Factor, was 2. I divided 6 by 2 and 10 by 2. I then got 3 and 5.
3 was the numerator, and 5 is the denominator.
Again, 16/10 in simplest form is 1 3/5.
One inch equals 8 miles, or in math terms, this is how we figure It out...

To find the scale we need to find what one inch equals on the map, dmto do this we divide both sides by 3 in. and get 8 miles in reality equals one map inch.
First you have to divide the 9 on both sides to get x alone. Next you would have to divide 117 and 9. (117÷9=13) . So x>13
