two fourths of a circle plus two tenths of a circle is what decimal part of a whole circle?
2/4 = 1/2 = 5/10
5/10 + 2/10 = 7/10 = 0.7
Maths stupid 🙄
2.4
To find the decimal part of a whole circle that is represented by two fourths of a circle plus two tenths of a circle, we can add these two fractions together and convert the resulting fraction to a decimal.
Let's start by finding a common denominator for the two fractions, which is 20.
Two fourths can be written as 2/4, and when multiplied by 5/5 (to get a denominator of 20), we get 10/20.
Two tenths can be written as 2/10, and when multiplied by 2/2 (to get a denominator of 20), we get 4/20.
Now we can add the two fractions together:
10/20 + 4/20 = 14/20.
To convert the fraction 14/20 to a decimal, divide the numerator (14) by the denominator (20):
14 ÷ 20 = 0.7.
Therefore, two fourths of a circle plus two tenths of a circle is equal to 0.7 or 7/10 of a whole circle as a decimal.
