• if you have fractions when in life would you need to use equivalent fractions ?
• If you wanted to divide something into equal parts...say you have six guests over and you are cutting it out and mom asks how much is left and there is 1/6 left.....without fractions you would be in a dilemma....does that help?
• can any number be a fractions?
• Yes. For example, `0.78` can be expressed as `78/100 = 39/50`. `23` can be expressed as `23/1` or as `46/2` if not simplified.
• Why didn’t they solve the last problem
• He did h was explaining that it wasn't even
• If I had 7 pet fishes 3 of them are red and 4 are gold how would I write this in fraction form and include all the given information (7 pets,3 red and 4 gold)
• One way to put this information in fraction form is 3/7 and 4/7 since 7 is the denominator which is the total number and the three and four are parts of 7.
• It does not help.
