To turn a fraction into a decimal you have to divide the numerator by the denominator. For example: 6/7 into a decimal would be 1.16666667 because 7 / 6 = <span>1.16666667
1/4 is one quarter. Four quarters makes a whole. Think of it as a dollar. One quarter is equal to 25 cents. Four quarters equals a dollar. So 1/4=0.25. 1/5 is fairly easy. Divide 100 by 5, and you get 20. The decimal could be written as 0.20, or just 0.2. They're pretty much the same thing. 1/6 is a little harder. You should just divide 100 by 6 on a calculator. But to help you finish the problem quicker, I'll just calculate it myself. It's about 0.167. But the full answer would be 0.1666... 1/8 is also a hard one. But you can just Google it haha. It's 0.125. 1/9 is also quite the challenge. I Googled this one as well. It's 0.111... 1/10 is actually very easy. Think of it as 10/100. That would be 0.10, or just 0.1. I did not use Google for this one. Now I'm getting a little lazy so I'll just give you the rest. 1/11=0.0909... 1/12=0.08333...
The relationship between speed (s), distance (d), and time (t) is s = d/t. Substituting the given information, we see that 105/t < 70105 < 70t1.5 < t So, the time will be AT LEAST 1.5 hours. Hope this helps.
