I'll walk you guys through the steps of the first question. k? 4/5 + 8/9 4/5 is estimated to be 1 whole. Same goes for 8/9. So in that case, 1+1=2. So your answer for 4/5 + 8/9 is 2.

Number 2. For number 2 of the quick check i'm walking you guys through we have a question, the question is 17/18-3/7. k? So we first start estimating. You can use a number line if you would like but for this question, looking at it I already know the answ...

Number 3 The question they are asking us to solve is 5x (2 3/5), First we don't have to do much with the 5 we have really. So the first number is just going to be 5. k. we don't need to do much with the 3/5, do we? BUT! the 2, we can do SOMETHING with it....

number 4. 25 7/8 / 2 7/8 = 9 Answer is 9.

3 2/3= 2/3=1+3=4 4 1/8=1/8=0+4=4 3 1/4=1/4=0+3=3 Then, add 4+4+3, you get 11.
