IGCSE Grade 6 Maths Dividing a whole number by 10 100 or 1 000 giving decimal quotients
|
Count the number of zeros in 100, we can see there are two zeros. So we move the decimal point two places to the left. Therefore 45.65 \\(\\div\\) 100 = 0.4565
Count the number of zeros in 1,000, we can see there are three zeros. So we move the decimal point three places to the left. So, 19 \\(\\div \\) 1,000 = 0.019.
Count the number of zeros in 100, we can see there are two zeros. So we move the decimal point two places to the left. 7,863 \\(\\div\\) 100 = 78.63.
When we divide a number by 10, 100, or 1000, we are decreasing its value by a factor of 10, 100, or 1000, respectively.
When dividing a whole number by a power of 10, the decimal point in the quotient is shifted to the right the same number of places as the exponent of 10
Count the number of zeros by 10, we can see there’s just one zero. So we move the decimal point one place to the left. Therefore the quotient is 9,806 \\(\\div\\) 10 = 980.6.
Count the number of zeros in 10, we can see there’s just one zero. So we move the decimal point one place to the left. Therefore, 3.4 \\(\\div\\) 10 = 0.34.
100 is a power of 10, and dividing by a power of 10 is the same as moving the decimal point in the dividend the same number of places to the right
Count the number of zeros in 1,000,we can see there are three zeros. So we put the decimal point three places to the left. Therefore 3,453\\(\\div\\) 1,000= 3.453.
To find the distance in tens of kilometers, we divide the total distance by 10
