KS2 Primary Maths Age 13-17 - Calculations: Word Problems - Explained

The video tutorial explains how to determine the number of pages left for Amina to read in a 276-page book after she has read one-third of it. It demonstrates two methods: dividing the total pages by three to find the pages read and subtracting from the total, and multiplying the pages read by two-thirds to find the pages left. The tutorial emphasizes that multiple solutions exist and encourages using the method one is comfortable with.

If a book has 276 pages and Amina has read 1/3 of it, how many pages has she read?

• 138 pages

• 276 pages

• 184 pages

• 92 pages

After reading 92 pages, how many pages are left for Amina to read?

• 184 pages

• 92 pages

• 276 pages

• 138 pages

What is the result of subtracting the pages Amina has read from the total pages of the book?

• 92 pages

• 184 pages

• 276 pages

• 138 pages

What is the alternative method to find the remaining pages Amina has to read?

• Add 1/3 to the total

• Subtract 1/3 from the total

• Calculate 2/3 of the book

• Calculate 1/3 of the book

Why might one choose the alternative method of calculating 2/3 of the book?

• It is more accurate

• It is quicker

• It is more complex

• It is the only method
