Q1.
Yesterday Mummy asked to divide a box of barfis into four equal parts. There are 16 barfis in the box. Draw a picture of 16 barfis and find 1/4 of the whole. How many barfis are in each part?
Answer
There are 4 barfis in each part.
A box of 16 barfis, drawn in 4 rows of 4.
16 barfis shared into 4 equal parts
16 = 4 + 4 + 4 + 4
Each part has 4 barfis
So 1/4 of 16 = 4 barfis
The 16 barfis split into 4 equal rows. Each row is one-fourth of the box.
Why it happens: Making 4 equal rows of the 16 barfis is the same as cutting the box into quarters. One row is one quarter.
Try This: 1/2 of 16 barfis is 8 barfis, and 1/8 of 16 barfis is 2 barfis.
Q2.
Rohan has a piece of ribbon to decorate his notebook. Mohan’s ribbon is one-fourth as long as Rohan’s ribbon. How long will Rohan’s ribbon be? Draw it.
Answer
Rohan’s ribbon is 4 times as long as Mohan’s ribbon.
Mohan’s ribbon, as printed in the book.
Mohan’s ribbon = 1/4 of Rohan’s ribbon
So Rohan’s ribbon = 4 pieces like Mohan’s
Mohan + Mohan + Mohan + Mohan = Rohan’s ribbon
Rohan’s ribbon drawn as four lengths of Mohan’s ribbon, one after the other.
Why it happens: One quarter fits into the whole exactly four times, so the whole is four of those quarters laid end to end.
Tip: If you measure Mohan’s ribbon as 5 cm, then Rohan’s ribbon is 5 + 5 + 5 + 5 = 20 cm.
