Question from MARLYN, a parent: My son have this question. I am trying to help him but i don't understand Which list shows number in order least to greatest? A. 07;2/3. 1/5;0.6 B 1/5;06; 07;2/3 C 1/5; 06; 2/3;0.7 D 2/5;0.6; 1/5;0.7 Thank in advance for your help Desperate mother |
Hi Marlyn,
You have the four numbers 0.7, 2/3, 1/5 and 0.6 and you want to put them in order, smallest to largest. The challenge is that some are decimal fractions and the others are common fractions. I would convert them all to decimal fractions and then compare them. For example if one of the common fractions were 2/5 then divide 5 into 2 to get 0.4 and if one of the common fractions were 3/7 then divide 7 into 3 to get 0.4286.
I hope this helps,
Penny
