1. The answer is B. 1, 232 is the answer to number 1 because all you have to do is do 154 x 8.
Steps: 154 x 8 ------
4 x 8 = 32 put the 2 down and carry the 3.
3 154 x 8 ----- 2
Next do 8 x 5 which equals 40 now add the 3 you carried, now you have 43. Put down the 3 and carry the 4, now you can erase the 3 that you had over the 5 just so you don't get confused.
4 154 x 8 ----- 32
Now 1 x 8 = 8 add the 4 and now you have 12 now just out down the 12 in front of 32.
4 154 x 8 ----- 1,232
2. You would do the exact same thing I just told you to do for 1, except instead of multiplying 154 and 8 you would multiply 1,493 and 4. The answer is 5,972 so A.
3. The answer is D which is 0. 95 since she missed 5 points out of 100. 0.95 is the same as 95%..
4. 602,163 < 620,163 the answer is B. 620,163 is bigger than 602,163 first just look at the ones place, the numbers are the same. Then just do the same thing until you have found a different number.
602,163 620,163 -- --
In the ten thousand place you can see that there is a 0 in 602,163 and a 2 in 620,163 so which is bigger, 0 or 2? 2 is bigger so the answer is B you would put < to make the statement true.
5. The answer is B. 30,300,200 because 3 x 100,000,00 would put the 3 right where the 1 is, what I mean is instead of the 1 being in 100,000,00 the 3 would be there. Its the same with 3 x 100,00 and 2 x 100. See, 2 x 100 would equal 200 so you just out the 2 in the hundredths place.
6. The answer is 800,000 because 755,082 rounded to the nearest ten thousands is 800,000. See if you have 55 and you were to found it you would round it to 60 because if you have a number that is 5 or greater you would round up, so in this cause a 5 is in the ten thousandths place so you round up...
