Today, we are going to learn about adding fractions.
Have a look at the in focus question below.
How much chocolate is being shared?
Do you think it is true that 1/3 + 1/9 = 2/9? How can you tell?
If you have the look at the image in the lets learn, you can see that the above statement is not true. They are not the same.
What we do know is that 1/9 + 3/9 = 4/9. This is the amount being eaten. We have converted 1/3 of the bar to 3/9. These fractions are equivalent.
To find the total, what do you think you need to do? Are the denominators the same?
How could we make them the same?
Do you notice that 5 and 10 can share the same denominator?
If we convert all the fractions so they share the same denominator, we know that 1/5 can be converted to 2/10 by multiplying both the numerator and denominator by 2.
Now, have a go at changing 2/5 so it shares the denominator of 10.
Well done if you got the answer 4/10.
If we add 2/10, 3/10 and 4/10 we get the answer 9/10.
Now have a go at the guided practice section.
