Answer:
the second one
Step-by-step explanation:
it does not say that both sides are parallel
4 divided by 2/3 equals 6. And 2/3 divided by 4 equals about 0.1666
First you would write it as 4/1 divided by 2/3, then you would you keep, change, flip. If you do not know how to keep,change,flip just keep the first fraction then change the division sign to multiplication then flip the last fraction. Then you should get the answer. And if you need to simplify make sure to do that.
Multiplying by 10 can be thought of as just adding a 0 to the right end of a number. If you have 2 and multiply it by 10, you get 20. For 1,234, you get 12,340. If you have 98,765, you can 987,650. Same thing applies for 100, 1000, 10000, ...., and so on. It moves it over depending on the number of 0's there are in the number. If it is 100, it will move two 0's over. For example, if you multiply 45 by 100, you get 4,500. The two zeros from 100 moved to the right side of the 45 to get 4500.
21 blocks, because if he uses 38 you subtract 17 and you get 21
