1/3 yard = 1/2 hr
  x  yard =  1 hr 

Okay, so if 1/3 of his yard is mowed in half an hour, "x" of his yard is mowed in an hour. 
1/3 yard is to 1/2 hr as "x" yard is to 1 hr 

Solve by cross multiplying: 
1/2x = 1/3 *1 
1/2x = 1/3
(divide both sides by 1/2) 
2/3 

Richard can mow 2/3 of his yard in one hour.

You can also figure this out by just realizing that 1/2 hr multiplied by 2 would give you 1 hr and then multiply 1/3 by 2 but it's good to get into the habit of solving things algebraically (or so I've been told).

natima [27]

Answer:

$695

Step-by-step explanation:

So if each camera costs $6.95 snd he wants 100 you would multiply by 100. And that would be 6.95×100=695 and a good trick I've learnt is that you just move the numbers 1 column to the left for each zero so if it was 10 you'd move all the numbers 1 column to the left. It is abit hard to explain but you're answer is there just thought that'd help in future.
