Write the missing dividend, divisor, or quotient for each division problem.
Problem 1 :
49.2 ÷ 10 = _____.
Solution :
49.2 ÷ 10
While dividing by 10, since we have one zero at the denominator, we have to move the decimal one digit backward. So, the answer will be 4.92.
Problem 2 :
49.2 ÷ _____ = 0.492.
Solution :
Since 49.2 is divided by 100, move the decimal point two digits to the left.
We get 0.492
So, the missing value is 100.
Problem 3 :
_____ ÷ 1,000 = 0.0492
Solution :
_____ ÷ 1,000 = 0.0492
While dividing by 1000, since we have three zeroes at the denominator, we have to move the decimal three digits backward.
Considering the non zero digits in the answer, we have 3 digits.
So, the missing value is 49.2.
Problem 4 :
49.2 ÷ 10,000 = _____.
Solution :
49.2 ÷ 10,000
While dividing by 10,000, since we have four zero at the denominator, we have to move the decimal four digits backward.
So, the answer will be 0.00492.
Problem 5 :
7.6 ÷ _____ = 0.76.
Solution :
Since 7.6 is divided by 10, move the decimal point two digits to the left.
We get 0.76
So, the missing value is 10.
Problem 6 :
_____ ÷ 100 = 0.076
Solution :
_____ ÷ 100 = 0.076
While dividing by 100, since we have two zero at the denominator, we consider the given answer we have to move the decimal two digits backward. So, the missing value is 7.6.
Problem 7 :
7.6 ÷ 1,000 = _____.
Solution :
7.6 ÷ 1,000
While dividing by 1000, since we have three zero at the denominator, we have to move the decimal three digits backward. So, the answer will be 0.0076.
Problem 8 :
7.6 ÷ _____ = 0.00076.
Solution :
In the answer, the decimal is moved four digits. So, we have to use four zeroes, that is 10000.
So, the missing value is 10,000.
Problem 9 :
Solution :
Problem 10 :
Solution :
Problem 11 :
Solution :
Problem 12 :
Solution :
You are given that 29 × 1374 = 39846
Use this information to find the answers to
Problem 1 :
39846 ÷ 29
Solution :
The given, 29 × 1374 = 39846
Let a = 29, b = 1374 and c = 39846
a x b = c
To find b :
b = c/a
b = 39846/29
b = 1374
So, the answer is 1374.
Problem 2 :
2.9 × 13.74
Solution :
Let a = 2.9 and b = 13.74
To find c :
c = a × b
c = 2.9 × 13.74
c = 39.846
So, the answer is 39.846.
Problem 3 :
0.29 × 13740
Solution :
Let a = 0.29 and b = 13740
To find c :
c = a × b
c = 0.29 × 13740
c = 3984.6
So, the answer is 3984.6.
Problem 4 :
398.46 ÷ 1.374
Solution :
Let b = 1.374 and c = 398.46
To find a :
a = c/b
a = 398.46/1.374
b = 290
So, the answer is 290.
Problem 5 :
58 × 1374
Solution :
Let a = 58 and b = 1374
To find c :
c = a × b
c = 58 × 1374
c = 79692
So, the answer is 79692.
