Year 5 Maths: Friday 1st May – Fractions as Operators

Bronze: There are two methods to work out each question. Your task is to solve the questions below and find out which method you find easier: 1. Multiplying the fraction, or 2. Finding the fraction of an amount.

You must work the answer out and then justify your reasoning and say WHY. Why is it easier? Why do you prefer that method? What is difficult about the other method?

Now solve the questions below:

Silver:

Use your knowledge from bronze to solve the following questions. Hint: Use the image layout ABOVE to see how you can fill in the gaps below.

  1. 2 lots of 1/10=2/10 1/10 of 2=2/10
    6 lots of 1/2=3 1/2 of 6=3
    8 lots of 1/4=2 1/4 of 8=2
    Silver,
    25×3/5=15 3/5 of 25=15
    6×2/3=4 2/3 of 6=4
    5×3/5=15/8 3/8 of 5=15/8

  2. 2 lots of 1/10 = 2/10 1/10 of 2 = 2/10
    6 lots of 1/2 = 3 1/2 of 6 = 3
    8 lots of 1/4 = 2 1/4 of 8 = 2

    Silver:
    25 x 3/5 = 15 3/5 of 25 = 15
    6 x 2/3 = 4 2/3 of 6 = 4
    5 x 3/8 = ? 3/8 of 5 = ?

  5. i have done the maths in my homework book and i found the division easier because when i wached the tutorial of Mr Iman i understood the second part more because by multiplying i found it a bit complicated.

  6. Silver
    3/5 of 25
    2/3 of 6
    3/8 of 5
    I have chosen these because 3/8 of 5 is a operator because operators are whole numbers that’s why I have c

    • No worries, I trust that you have done the reasoning element in your book. Thank you for apologising. Be careful with your vocabulary. Operators are not whole numbers, integers are whole numbers :)

  7. Bronze
    25 x 3/5 = 75/5 or 15
    3/5 of 25 = 75 this way is easier for this question
    6 x 2/3 = 12/3 or 4
    2/3 of 6 = 4 this way is easier for this question
    5 x 3/8 = 15/8
    3/8 of 5 Im not sure about this one

    2 lots of 1/10 = 2/10 or 1/5
    1/10 of 2 = 5
    6 lots of = 3 im not sure about this one
    1/2 of 6 = 3
    8 lots of 1/4 = 8/4 or 2
    1/4 of 8 = 2

  8. I like fractions of amount better because the bar model helps me to understand it better.
    Multiplying Fractions
    25 x 3/5=15
    25 /1 x 3/5 = 75/5
    75 / 5 = 15
    Fractions of Amounts
    3/5 of 25 =15
    25/5 = 5
    5 x 3 =15

    • I think you may be a little confused. Operators are not whole numbers. Think about how the fraction is being used to solve the question. Ie. what does the numerator and the denominator represent? What is the whole?

  9. Silver,.
    3/5 of 25
    2/3 of 6
    3/8 of 5
    I have chosen these because 3/8 of 5 is a operator because operators are whole numbers that’s why I have chosen these.

    • Well Abdi, I do not remember “I have done it” being the answer to the reasoning question? If you have written your response in your book then please send it over by email. How do you solve these questions?

    • Abdi, you need to send your work to us please.
      You need to give an answer for your reasoning. Make sure you are reading the blogs properly and then answering the questions in your homework book. I expect this to be done at your best.
