Type into a calculator 2000*(3/8)
The answer is 750
So distance=rate x time and if we rearrange this to find the time we get time=distance/rate. Now we can just plug in the numbers.
3.54*10^7/3*10^8=time(seconds)
To solve this we can just divide the parts of the scientific notation separately.
3.54/3=1.18
10^7/10^8=1/10
Now we just multiply our answers together because we separated them before we divided.
1.18*1/10=.118
So the answer is .118 seconds
1. Multiply length times width as if they were integer number:
Now place the decimal point. To do it we have to keep in mind that the result will have as many decimals as the sum of the decimals of each number. In this case, only the width had one decimal, it means that the result will only have one decimal:
Number 7 is probably 4 because x is on the top which means it’s greater than 7
