first we identify wich one is in the tenth position, In this case it is the 6. Now we look at the number next to our number in the ones position. In this case is 9. from 0 to 4 our number would stay the same but from 5-9 it changes so our answer is
44,770

When rounding to the nearest ten, always check up onthe ones place value. 9 is the ones place value digit: 44769

As I said before on the other answer: 4 or less, round down,5 or more, round up.

44769 rounded to the nearest ten is 44770.

Keith uses 18 cherries and three peaches to make a pie feeling Lena uses it and equivalent ratio of cherries to peaches when she makes pie filling came Lena use a ratio I have 21 chairs to six peaches explain

Answers

Answer:

No, she cannot use a ratio of 21 to 6. You can figure this out in a few different ways. First you can simplify down the fraction 18/3, to get 6/1. 6/1 does not equal 21/6, because 21/6 equals 7/2. However, 6/1 it does equal 36/6. You could also noticed that three doubles to make six, yet 18 does not double to make 21. :D
