Q1.
40 ÷ 10 = ____ 400 ÷ 10 = ____ 400 ÷ 100 = ____
Answer
ProblemAnswer
40 ÷ 10 (how many tens in 40?)4
400 ÷ 10 (how many tens in 400?)40
400 ÷ 100 (how many hundreds in 400?)4
40 = 4 Tens  →  40 ÷ 10 = 4
400 = 40 Tens → 400 ÷ 10 = 40
400 = 4 Hundreds → 400 ÷ 100 = 4
Why it happens: Dividing by 10 asks how many tens there are, and dividing by 100 asks how many hundreds.
Q2.
4 ÷ 2 = ____ 40 ÷ 20 = ____ 400 ÷ 200 = ____
Answer
ProblemAnswer
4 ÷ 22
40 ÷ 202
400 ÷ 2002
4 ÷ 2 = 2
40 ÷ 20 = 4 Tens ÷ 2 Tens = 2
400 ÷ 200 = 4 Hundreds ÷ 2 Hundreds = 2

All three answers are the same.

Why it happens: Both numbers grew ten times each time. Sharing ten times more among ten times bigger groups gives the same answer.
Q3.
400 ÷ 2 = ____ 400 ÷ 20 = ____ 400 ÷ 200 = ____
Answer
ProblemAnswer
400 ÷ 2200
400 ÷ 2020
400 ÷ 2002
400 ÷ 2 = 200 (half of 400)
400 ÷ 20 = 40 Tens ÷ 2 Tens = 20
400 ÷ 200 = 4 Hundreds ÷ 2 Hundreds = 2

Each time the group is ten times bigger, so the answer is ten times smaller: 200, 20, 2.

Why it happens: The same 400 shared into bigger and bigger groups gives fewer and fewer groups.
Note: 400 ÷ 200 is printed twice on this page — once in the middle column and once here. Both give 2.
Q4.
1. Manku the monkey sees 870 bananas in the market. Each bunch has 10 bananas. How many bunches are there in the market? _______ (Write the division statement.)
Answer
Division statement: 870 ÷ 10 = 87
870 = 87 Tens
Each bunch is one ten.

There are 87 bunches in the market.

Why it happens: Every bunch takes away exactly 10 bananas, so the answer is simply the number of tens in 870.
Q5.
2. Rukhma Bi wants to distribute ₹1000/- equally among her 10 grandchildren on the occasion of Eid. How much money will each of them get? ________
Answer
Division statement: ₹1000 ÷ 10 = ₹100
1000 = 10 Hundreds
Give 1 Hundred to each child.

Each grandchild gets ₹100.

Why it happens: One thousand is ten hundreds. Ten children, one hundred-rupee note each.
