Hello! These are a set of challenges set to me by my teacher, this sheet contains a lot of fractions, in fact its even stage 7!
If you need help for kumon maybe you could take some notes. (all of them aren't exact so feel free to correct me)
Hey jai! like like your work, it looks hard. but I know its easy because i've done it to.๐๐๐๐๐๐
ReplyDeleteHi Jai, really good thinking shown in the ratio marbles question. To solve the equivalent fractions question (Question 4), this is what you do:
ReplyDelete5/8 = ?/40
I know that 8x5=40 (Denominator)
We do the same to the numerator: 5x5=25
So the equivalent fraction is 25/40
