Practice makes perfect
We want to find the decimal equivalent of 720. To write a fraction as a decimal, we divide the numerator by the denominator.
division
We found that 720 expressed as a decimal is 0.35.
We want to find the decimal equivalent of - 2320. To write a fraction as a decimal, we will ignore the sign and divide the numerator by the denominator.
division
We found that 2320 expressed as a decimal is 1.15. This means that - 2320 can be expressed as - 1.15.
We want to find the decimal equivalent of 118. To write a fraction as a decimal, we divide the numerator by the denominator.
Applet to compute the division of two numbers
The quotient is a repeating decimal, so we draw a horizontal bar on top of the repeated digits. 1 Ă· 18 = 0.05
We want to find the decimal equivalent of - 6022. To write a fraction as a decimal, we will ignore the sign and divide the numerator by the denominator.
Applet to compute the division of two numbers
The quotient is a repeating decimal, so we draw a horizontal bar on top of the repeated digits. 60 Ă· 22 = 2.72 We found that 6022 expressed as a decimal is 2.72. This means that - 6022 can be expressed as - 2.72.
