The question
Question: write 7/100 as a decimal.
7100
1 Write the decimal
100 has 2 zeros.
So the decimal has 2 digits after the point.
We fill the gap with a 0 after the point.
100: 2 zeros → 2 digits after the point
7 hundredths is 0.07.
= 0.07
2 Check
Let's check: the decimal times the bottom should give the top.
0.07 times 100.
Check: 0.07 × 100
Forget the points: 7 times 100 is 700.
The numbers have 2 digits after the point.
So the answer has 2 too: 7.00, which is 7.
7 × 100 = 700 → 7.00
We get 7, the top.
So the answer is right!
0.07 × 100 = 7
Let's look back.
First: write the decimal.
Last: check.
Answer
= 0.07
